class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the most fundamental points physicians consider when evaluating heart rhythm during childhood is that the heart rate constantly changes depending on the child&#8217;s stage of growth, current level of physical activity, sleep or wakefulness, and even body temperature. From birth onward, the human heart tends to slow down as the body grows. While it is normal for a newborn baby&#8217;s heart to beat at a high rate per minute while at rest, the same heart rate may be interpreted as a sign of a rapid heartbeat in an adolescent. In young children between one and three years of age, the resting heart rate continues to remain relatively high, whereas this value gradually decreases by school age. During adolescence, and especially in young people who participate in sports requiring regular exertion, the resting heart rate may fall to even lower levels, and this is considered a healthy adaptation of the athlete&#8217;s heart.<\/p>\n<p>Children also have a natural fluctuation in heart rhythm associated with breathing, known as sinus arrhythmia. When a child takes a deep breath, the heart rate increases slightly, while the heartbeat slows during exhalation. This physiological fluctuation is not regarded as a sign of disease; on the contrary, it is considered a very positive indicator that the heart is working in great harmony with the autonomic nervous system. Due to these age-specific changes during development, pediatric cardiology evaluations are made by taking into account the specific reference values of each age group.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_Heart_Rhythm_Disorder_Arrhythmia_Develop\"><\/span>How Does Heart Rhythm Disorder (Arrhythmia) Develop?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The heart functions like a highly advanced and coordinated system that produces its own electricity. Microscopic tissue located in the upper right chamber and serving as the heart&#8217;s natural pacemaker produces electrical impulses at regular intervals. These impulses travel first to the upper chambers and then to the lower chambers through the heart&#8217;s special and delicate conduction pathways, supporting the contraction of the heart muscle in a regular sequence and the pumping of blood throughout the body.<\/p>\n<p>This system enables every cell of the heart to work in harmony, just as a conductor directs the instruments of an orchestra.<\/p>\n<p>Heart rhythm disorder (arrhythmia) usually develops when a disruption or a type of electrical short circuit occurs at one of these electrical production or conduction stages. Sometimes this natural stimulation center may produce electrical signals that are far too fast or too slow, independently of the body&#8217;s needs. At other times, an additional congenital extension of electrical tissue between the lower and upper chambers of the heart may cause the electrical current to enter a vicious cycle, suddenly increasing the heart rate far above its resting level. When the heart enters this cycle and beats very rapidly, it has difficulty finding enough time to relax and fill with fresh blood. This may make it harder for the heart to nourish its own muscle tissue and may also disrupt the delivery of sufficient oxygenated blood to vital organs. In conditions where the heart beats too slowly, a reduction in the overall blood flow to tissues and organs is observed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Main_Causes_of_Heart_Rhythm_Disorder_Arrhythmia_Development_in_Children\"><\/span>What Are the Main Causes of Heart Rhythm Disorder (Arrhythmia) Development in Children?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><iframe title=\"Do\u011fu\u015ftan Gelen Kalp Hastal\u0131klar\u0131 Nelerdir? | Prof. Dr. Cansaran Tan\u0131d\u0131r\" width=\"1020\" height=\"574\" src=\"https:\/\/www.youtube.com\/embed\/E9HygWGJ9EE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Rhythm problems encountered in children are generally examined within a broad framework based on structural characteristics, genetic factors at the cellular level, or various acquired external factors. In children with a small congenital hole in the heart or structural differences in the blood vessels, changes in intracardiac pressure may occur because the dynamics of blood flow within the heart are altered. Enlargement of the heart chambers beyond normal over time may stretch the delicate electrical conduction lines extending between the heart muscle cells, potentially triggering these conduction problems. Fine scar tissue remaining from heart operations performed in previous years may also create small obstacles along the electrical pathways within the heart, changing the direction of electrical flow and predisposing to rhythm irregularities.<\/p>\n<p>In addition, even if a child&#8217;s heart anatomy appears flawless, genetic differences in the functioning of channels that allow minerals to pass through the cell membrane may lead to rhythm irregularities. These cellular conditions are called channelopathies. Among acquired causes, viral infections affecting the heart muscle are prominent. Such infections may mildly affect the heart muscle and cause extra heartbeats. Temporary imbalances in vital minerals in the blood such as calcium, potassium, and magnesium, or changes in the activity of the thyroid gland, are also possible causes of rhythm fluctuations. High fever, insufficient fluid intake, emotional stress, side effects of certain cold and flu medications, and especially caffeinated beverages frequently consumed by young people may accelerate the heart rhythm.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Symptoms_of_Heart_Rhythm_Disorder_Arrhythmia_in_Infants\"><\/span>What Are the Symptoms of Heart Rhythm Disorder (Arrhythmia) in Infants?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><iframe title=\"\u00c7ocuklarda Kalp Ritim Bozuklu\u011fu G\u00f6r\u00fcl\u00fcr M\u00fc? | Prof. Dr. Cansaran Tan\u0131d\u0131r\" width=\"1020\" height=\"574\" src=\"https:\/\/www.youtube.com\/embed\/X4fVwrPhcJ0?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe><\/p>\n<p>Because newborns and young infants whose communication skills have not yet developed cannot express the unusual sensations they experience in words, symptoms in this age group may be detected by families through very careful daily observation. The warning signs encountered during infancy are often understood indirectly. Sudden physical changes without an apparent cause, disruptions in sleep patterns, and loss of appetite may be signs of electrical changes in the heart.

They may describe the sensation of the heart beating very rapidly as a bird flapping its wings inside the chest or the heart doing somersaults. Physical strain that suddenly develops during physical education classes, while running in the schoolyard, or during competitive sports is especially important for physicians. Sudden declines in the child&#8217;s general sports performance and prolonged exhaustion after exertion are clues that should be taken seriously. The symptoms of heart rhythm disorder (arrhythmia) that may occur during exertion or at rest in older children and adolescents are listed below:<\/p>\n<ul>\n<li aria-level=\"1\">A severe sensation of palpitations in the chest<\/li>\n<li aria-level=\"1\">Sudden onset of chest pain<\/li>\n<li aria-level=\"1\">The need to take deep breaths<\/li>\n<li aria-level=\"1\">Shortness of breath or a choking sensation<\/li>\n<li aria-level=\"1\">Sudden severe weakness<\/li>\n<li aria-level=\"1\">Darkening of vision<\/li>\n<li aria-level=\"1\">Dizziness<\/li>\n<li aria-level=\"1\">Brief fainting<\/li>\n<li aria-level=\"1\">Becoming tired quickly during exercise<\/li>\n<li aria-level=\"1\">A sensation of irregular beats in the chest<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"What_Consequences_May_Occur_If_Heart_Rhythm_Disorder_Arrhythmia_Is_Not_Treated\"><\/span>What Consequences May Occur If Heart Rhythm Disorder (Arrhythmia) Is Not Treated?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When such electrical irregularities in the heart rhythm are not evaluated in time and managed with appropriate medical approaches, they may have exhausting and damaging effects on the heart&#8217;s overall anatomy and daily functions. High-speed heartbeats that continue for months without being noticed externally may prevent the heart muscle from resting adequately throughout the day and cause it to become fatigued like a muscle constantly running a marathon. Over time, the heart chambers may enlarge, and the heart&#8217;s ability to eject blood into the body may weaken. This state of fatigue may pave the way for the development of clinical conditions that make it difficult for the heart to provide the energy required by the body.<\/p>\n<p>However, thanks to advances in pediatric cardiology, it is known that these signs of cardiac fatigue can largely be reversed when the heart rate is brought under control with medications or other methods through early diagnosis. On the other hand, severe rhythm attacks in which the heart cannot pump blood effectively may cause blood pressure to fall far below normal and reduce blood flow to tissues, including the brain. When blood does not move through the heart chambers at its natural speed and fluidity, the risk of blood cells clustering together and forming clots may increase. In rarer cases, sudden and chaotic disruptions in the heart&#8217;s electrical system may interrupt its blood-pumping function and create life-threatening risks requiring emergency intervention.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_Medical_Methods_Are_Used_to_Diagnose_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>Which Medical Methods Are Used to Diagnose Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When any rhythm problem is suspected in children, a series of painless, reliable, and modern technological tests are used in hospitals to determine the source of the problem. These tests reveal both the electrical map and the physical structure of the heart.<\/p>\n<p>The first step in this evaluation is generally electrocardiography, in which the heart&#8217;s electrical waves are displayed on a computer screen or recorded on paper with the help of small soft stickers attached to the chest, arms, and legs. It takes only a few seconds and provides the physician with very valuable information about the heart&#8217;s electrical state at that moment. To examine whether there is any problem in the anatomy of the heart, the functioning of the valves, and the thickness of the walls, an echocardiography device operating with advanced sound waves is used. This ultrasound method is applied to every patient to understand whether there is a hidden structural problem accompanying the rhythm irregularity.<\/p>\n<p>In situations requiring continuous monitoring, portable devices attached to the child&#8217;s chest that can record electrical activity continuously from twenty-four hours to several weeks are used. While the child continues daily activities at home, at school, or during sleep, this small device records every heartbeat in its memory. Event recorder devices, which record only when the child presses a button during a sensation of palpitations, also provide physicians with great convenience in capturing less frequent attacks. Exercise tests are also used to observe the child&#8217;s rhythm during exertion by continuously monitoring the child while walking on a treadmill that accelerates according to a specific protocol. In more complex diagnostic cases, electrophysiological mapping is performed by advancing very thin, flexible tubes through the groin into the heart, and the center of the problem is identified at the cellular level.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Can_Be_Done_During_Sudden_Heart_Rhythm_Disorder_Arrhythmia_Attacks_at_Home\"><\/span>What Can Be Done During Sudden Heart Rhythm Disorder (Arrhythmia) Attacks at Home?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Certain simple physical maneuvers may provide beneficial results during sudden attacks of very rapid palpitations that begin at home when the child is conscious, able to communicate with the surroundings, and appears to be in good general condition. These maneuvers aim to stimulate the branch of the autonomic nervous system that slows the heart, helping the rapid rhythm settle within a short time and supporting the heart&#8217;s return to its normal cycle. However, it is extremely important for parents to remain calm while applying these methods, observe the child&#8217;s overall condition carefully, and pay attention to whether there is any confusion. If these home practices do not produce the expected result within a short time, professional medical assistance must be sought without delay. These supportive actions that can be applied at home include:<\/p>\n<ul>\n<li aria-level=\"1\">Splashing cold water on the face<\/li>\n<li aria-level=\"1\">Placing an ice pack around the forehead and nose<\/li>\n<li aria-level=\"1\">Taking deep and calm breaths<\/li>\n<li aria-level=\"1\">Closing the mouth and bearing down with the abdominal muscles<\/li>\n<li aria-level=\"1\">Pinching the nose, puffing out the cheeks, and trying to exhale<\/li>\n<li aria-level=\"1\">Coughing forcefully<\/li>\n<li aria-level=\"1\">Safely stimulating the gag reflex<\/li>\n<li aria-level=\"1\">Resting in a semi-seated position<\/li>\n<li aria-level=\"1\">Slightly elevating the legs with the help of a pillow<\/li>\n<li aria-level=\"1\">Waiting in a calming environment<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_a_Heart_Rhythm_Disorder_Arrhythmia_Crisis_Managed_in_the_Hospital\"><\/span>How Is a Heart Rhythm Disorder (Arrhythmia) Crisis Managed in the Hospital?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In children brought to the hospital emergency department during an attack, physicians and nurses follow a safe and highly systematic medical approach to terminate the rapid palpitations. As the first step, an intravenous line is usually opened in the child&#8217;s arm or the back of the hand, and special medications with a very rapid onset of action are administered. When these medications reach the heart&#8217;s electrical system, they act within seconds, allowing electrical conduction to pause for a very brief moment and then enabling the heart&#8217;s natural pacemaker to resume operation in a normal rhythm.<\/p>\n<p>If the first medication administered is insufficient or the rhythm problem restarts within a short time, intravenous medications with a longer duration of action that balance the electrical sensitivity of the heart muscle through different mechanisms may be required. If the rhythm irregularity has lowered the child&#8217;s blood pressure below safe limits, caused extreme pallor of the skin, or led to confusion, waiting for the medications to enter the circulation and take effect may result in lost time. In such very urgent situations, a procedure called cardioversion is performed in the hospital by delivering a very brief dose of electrical energy through the chest wall, calculated according to the child&#8217;s weight. This special procedure largely supports the resetting of the existing chaotic electrical activity in the heart and allows the natural system to regain control.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Can_Heart_Rhythm_Disorder_Arrhythmia_in_Children_Be_Treated_with_Medication\"><\/span>Can Heart Rhythm Disorder (Arrhythmia) in Children Be Treated with Medication?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Long-term oral medication treatments are frequently prescribed to suppress arrhythmias that affect daily life and tend to recur continuously in children, and to prevent palpitation attacks. One of the most important points families should know during this process is that these rhythm medications do not permanently eliminate the additional cellular pathway or structural cause underlying the rhythm disorder, but they largely prevent attacks from occurring by balancing the heart&#8217;s electrical system while they are being used. Taking the medications regularly and at the times recommended by the physician plays a key role in the success of treatment.<\/p>\n<p>A very promising natural process occurs in certain specific rhythm problems that begin especially in the fetal period or during the first months of life. As the baby grows and the electrical conduction pathways in the heart mature, the likelihood that the rhythm disorder will disappear spontaneously over time is quite high. For this reason, prolonged and patient medication follow-up is provided for children in younger age groups. When the child reaches a certain size and age, medication doses are gradually reduced and discontinued over several weeks under physician supervision, and it is observed whether the heart rhythm functions normally without medication support. While some children complete this medication-free trial period without problems, different advanced treatment methods may be considered appropriate in cases where the rhythm disorder continues.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"In_Which_Situations_Is_a_Pacemaker_Used_in_the_Treatment_of_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>In Which Situations Is a Pacemaker Used in the Treatment of Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Permanent pacemakers are used in specific situations where the transmission of electricity produced in the upper chambers of the heart to the lower chambers is significantly slowed or completely interrupted. The use of these devices becomes essential in cases where the heart&#8217;s natural operating rate slows to a level that cannot meet the body&#8217;s oxygen requirements, especially those of the brain, and causes frequent dizziness or fainting attacks. These tiny electronic generators, usually placed under the skin in the area just below the collarbone through a delicate surgical procedure, continuously monitor the heart&#8217;s electrical activity through thin and flexible wires extending through the blood vessels into the heart.<\/p>\n<p>When the heartbeat is detected to have fallen below the programmed safe limits or paused, the device sends gentle electrical impulses within milliseconds, ensuring that the heart works regularly and pumps blood. On the other hand, a different technology is used in patients who are at risk of sudden rhythm loss and have genetic abnormalities in the heart&#8217;s electrical channels. Shock devices that continuously analyze the heart rhythm day and night and automatically deliver shock energy to the heart when they detect a life-threatening, extremely rapid vibration may be preferred. With advancing technology, the size of these devices has become considerably smaller, and they can be safely implanted in a manner compatible with children&#8217;s active lifestyles.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_Catheter_Ablation_Performed_for_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>How Is Catheter Ablation Performed for Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>One of the highly effective medical solutions offered by medicine for children whose palpitation complaints continue despite medication, who are adversely affected by potential medication side effects, or whose education and sports lives are restricted due to arrhythmias is the catheter ablation procedure. Ablation is essentially an advanced interventional method performed entirely through the blood vessels without requiring the patient&#8217;s chest to be opened.<\/p>\n<p>Pediatric cardiology specialists enter through the vessels in the groin using specially designed, millimeter-thin, soft, and steerable catheters and slowly advance them into the heart. The electrical currents on the inner surface of the heart are mapped on special computer screens, and the precise location of the millimeter-sized tissue creating the short circuit that causes the rhythm disorder is determined with great accuracy. Then heat energy delivered through radiofrequency from the tip of the catheter (RF ablation) or cooling energy using a special gas (cryoablation) is applied to this small targeted tissue point, rendering the abnormal electrical pathway nonfunctional. This method, most commonly used in children approaching school age, can also be successfully applied to small infants in well-equipped centers when medically necessary. It is a permanent treatment option that aims to eliminate the source of arrhythmias at the cellular level.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Advantages_of_Radiation-Free_Methods_in_the_Treatment_of_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>What Are the Advantages of Radiation-Free Methods in the Treatment of Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In previous years, fluoroscopy devices emitting X-rays were extensively used during ablation procedures to visualize the catheters inside the heart, guide them between the chambers, and reach the correct target. However, the bodies, tissues, and rapidly dividing cells of growing children are much more sensitive to the cumulative side effects of radiation compared with adult bodies. Radiation exposure may carry the risk of predisposing to undesirable cellular changes even many years later.<\/p>\n<p>One of the most encouraging developments in modern pediatric cardiology is the integration of three-dimensional electroanatomical mapping systems into medical practice, reducing fluoroscopy use to almost zero or allowing the procedure to be performed from beginning to end without any radiation. Thanks to this advanced technology, the internal chambers of the heart are modeled on a computer screen as a three-dimensional and colored map, just like a navigation system. The team performing the procedure can monitor the location of the catheters inside the heart on the three-dimensional screen with millimeter precision without exposing the patient to radiation. The problematic area can be identified and treated much more safely. These systems also provide substantial guidance to physicians even in children who have previously undergone open heart surgery and whose heart anatomy has changed. Enabling growing children to complete these vital procedures while being protected from radiation is an extremely important step toward safeguarding their future health.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Is_the_Freezing_Method_Preferred_in_Ablation_for_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>Why Is the Freezing Method Preferred in Ablation for Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While the targeted tissue is usually destroyed with heat energy in conventional ablation methods, in some children the abnormal pathways causing arrhythmias may be located very close to the completely healthy and vital main electrical cables of the heart. The possibility of this high temperature spreading to the surrounding healthy tissues during the heating process may carry the risk of unintentionally damaging the heart&#8217;s normal conduction system. If such a situation occurs, heart block may develop and the patient may need to use a pacemaker for life.<\/p>\n<p>To minimize this sensitive risk and maximize safety in children, cryoablation technology using freezing is employed. In this advanced system, when the tip of the catheter contacts the target tissue, it is first cooled to approximately minus thirty degrees, temporarily numbing the tissue and rendering it nonfunctional. During this initial cooling stage, the heart&#8217;s electrical responses are monitored second by second on the screens. If the unwanted arrhythmia stops and the heart&#8217;s normal system is not adversely affected by the cold in any way, the temperature is lowered to minus seventy or eighty degrees and the permanent intervention is safely completed. If a slight slowdown or risk in the normal system is noticed at minus thirty degrees, the procedure is stopped immediately, and the tissue thaws within seconds and returns to its previous healthy state. In this way, interventions performed in risky regions become much safer.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Should_Change_in_the_Daily_Lives_of_Children_with_Heart_Rhythm_Disorder_Arrhythmia\"><\/span>What Should Change in the Daily Lives of Children with Heart Rhythm Disorder (Arrhythmia)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In addition to medical treatments, medications, or ablation procedures, a supportive lifestyle established at home, school, and in the child&#8217;s overall social life should be regarded as an integral part of the process for a child experiencing a rhythm disorder. School-related stress, intense exam anxiety, long hours spent in front of screens, or irregular sleep habits encountered by growing children throughout the day are among the leading environmental factors that can directly and negatively affect the heart rhythm. Therefore, it is very important to ensure that children sleep for a sufficient amount of time to achieve mental and physical rest.<\/p>\n<p>Physical activity is not completely removed from the child&#8217;s life, but certain sports may be reduced according to the cardiologist&#8217;s recommendations. Families listening carefully to their children&#8217;s daily complaints, not neglecting necessary hospital check-ups, and making small but effective changes to the family&#8217;s general dietary habits greatly support the treatment process in a positive direction. The basic points recommended for attention in daily life during this process are as follows:<\/p>\n<ul>\n<li aria-level=\"1\">Getting uninterrupted and high-quality sleep<\/li>\n<li aria-level=\"1\">Establishing regular sleep hours<\/li>\n<li aria-level=\"1\">Reducing exam and school stress<\/li>\n<li aria-level=\"1\">Limiting brewed tea consumption<\/li>\n<li aria-level=\"1\">Avoiding coffee and similar beverages as much as possible<\/li>\n<li aria-level=\"1\">Limiting chocolate and cocoa-containing foods<\/li>\n<li aria-level=\"1\">Avoiding high-caffeine energy drinks<\/li>\n<li aria-level=\"1\">Avoiding sports requiring excessive exertion<\/li>\n<li aria-level=\"1\">Taking light walks approved by the physician<\/li>\n<li aria-level=\"1\">Taking prescribed medications on time without interruption<\/li>\n<li aria-level=\"1\">Attending regular physician check-ups<\/li>\n<li aria-level=\"1\">Drinking a sufficient amount of water<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Heart rhythm disorder (arrhythmia) is a condition in which the heartbeat becomes irregular, rises far above or falls far below the physiological limits considered normal, or the heart beats irregularly as a result of disruptions in the heart&#8217;s natural electrical stimulation system.
