Arrhythmia in children is a condition in which the normal beating pattern of the heart is disrupted in the form of fast, slow, or irregular beats, and it may be congenital or acquired. This condition appears with symptoms such as palpitations, weakness, fainting, and chest pain and requires pediatric cardiology evaluation.<\/p>\n
Symptoms of arrhythmia in children vary according to age group and may be observed in babies as feeding difficulty, cyanosis, and restlessness. In older children, palpitations increasing with exertion, dizziness, and sudden loss of consciousness may occur. The duration and frequency of symptoms are decisive in the diagnostic process.<\/p>\n
Causes of heart rhythm disorders in children include congenital heart diseases, electrolyte imbalances, infections, and genetic conduction system diseases. In addition, some medications and metabolic disorders may also predispose to the development of arrhythmia. Detailed history and test planning are important.<\/p>\n
Treatment methods for arrhythmia in children vary according to the type and severity of the arrhythmia and may include medication therapy, catheter ablation, or rarely permanent pacemaker implantation. Regular cardiological follow-up, lifestyle adjustments, and control of risk factors increase treatment success.<\/p>\n
| What You Need to Know<\/td>\n | Information<\/td>\n<\/tr>\n |
| Definition<\/td>\n | Arrhythmia in children is a condition in which the heart rate or rhythm becomes abnormal as a result of irregularities in the normal electrical conduction system of the heart. Heartbeats may be faster than normal (tachycardia), slower (bradycardia), or irregular.<\/td>\n<\/tr>\n |
| Incidence<\/td>\n | It can be seen in every age group from the neonatal period to adolescence. Some arrhythmias may also occur in healthy children without structural heart disease.<\/td>\n<\/tr>\n |
| Symptoms<\/td>\n | A feeling of palpitations, chest pain, dizziness, fainting (syncope), weakness, getting tired easily, shortness of breath, sucking difficulty in babies, restlessness, paleness, or cyanosis. Some mild rhythm disorders may not cause symptoms.<\/td>\n<\/tr>\n |
| Emergency Symptoms<\/td>\n | Loss of consciousness, severe shortness of breath, cyanosis, fainting accompanied by chest pain, excessive acceleration or slowing of heartbeats. These situations require urgent medical evaluation.<\/td>\n<\/tr>\n |
| Causes<\/td>\n | Congenital heart diseases, heart muscle diseases (cardiomyopathy), electrolyte imbalances, infections (especially myocarditis), fever, thyroid diseases, genetic syndromes, some medications, and rarely trauma.<\/td>\n<\/tr>\n |
| Genetic Factors<\/td>\n | Inherited rhythm disorders such as Long QT syndrome and Brugada syndrome may be seen more frequently in children with a family history.<\/td>\n<\/tr>\n |
| Risk Factors<\/td>\n | Family history of sudden cardiac death, congenital heart disease, previous heart surgery, intense sports activity, electrolyte loss (vomiting, diarrhea), use of certain medications.<\/td>\n<\/tr>\n |
| Diagnostic Methods<\/td>\n | Physical examination, electrocardiography (ECG), Holter monitoring (24-hour rhythm recording), event recorder devices, echocardiography, exercise test, and electrophysiological study when necessary.<\/td>\n<\/tr>\n |
| ECG Findings<\/td>\n | Increase or decrease in heart rate, conduction delays, extra beats (extrasystoles), QT prolongation, or specific tachycardia patterns may be seen.<\/td>\n<\/tr>\n |
| Types of Tachycardia<\/td>\n | Supraventricular tachycardia (SVT), ventricular tachycardia, atrial tachycardia, sinus tachycardia. SVT is the most common in children.<\/td>\n<\/tr>\n |
| Types of Bradycardia<\/td>\n | Sinus bradycardia, atrioventricular blocks (1st, 2nd, or 3rd degree block).<\/td>\n<\/tr>\n |
| Treatment Approach<\/td>\n | Treatment is determined according to the underlying cause and the type of rhythm disorder. While some mild arrhythmias only require observation, serious conditions require active treatment.<\/td>\n<\/tr>\n |
| Medication Therapy<\/td>\n | Antiarrhythmic drugs (for example beta blockers), electrolyte-regulating treatments, or medications for the underlying disease may be used.<\/td>\n<\/tr>\n |
| Interventional Treatment<\/td>\n | Catheter ablation is an effective method, especially in recurrent and medication-resistant supraventricular tachycardias.<\/td>\n<\/tr>\n |
| Device Therapy<\/td>\n | A pacemaker may be applied in permanent bradycardia or advanced conduction blocks; an implantable cardioverter defibrillator (ICD) may be applied in serious ventricular arrhythmias.<\/td>\n<\/tr>\n |
| Lifestyle Recommendations<\/td>\n | Regular cardiology follow-up, compliance with the physical activity level recommended by the doctor, adequate fluid intake, maintenance of electrolyte balance, and avoidance of triggering medications.<\/td>\n<\/tr>\n |
| Sports and Activity<\/td>\n | The decision to participate in sports should be evaluated by a cardiology specialist according to the type and severity of the arrhythmia. Restrictions may be required in some arrhythmias.<\/td>\n<\/tr>\n |
| Prognosis<\/td>\n | Most childhood arrhythmias can be controlled with appropriate treatment. Early diagnosis and regular follow-up reduce the risk of complications.<\/td>\n<\/tr>\n |
| Possible Complications<\/td>\n | Recurrent fainting, heart failure, rarely sudden cardiac death. Careful monitoring is required especially in genetic arrhythmias.<\/td>\n<\/tr>\n |
| Prevention<\/td>\n | Family screening in the presence of genetic predisposition, regular check-ups, maintenance of electrolyte balance, and avoidance of risky medications are important.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n |
