Tachyarrhythmias are common cardiac arrhythmias in newborns and infants. The majority of tachyarrhythmias presenting in infancy depend on the presence of an accessory pathway. In one‐third of patients, tachyarrhythmia never recurs after 1 year of age, but heart failure may develop more easily in neonates and infants depending on the duration, mechanism, and rate of tachycardia.Patients usually present with non‐specific symptoms, such as pallor, difficulty feeding, tachypnea, and excessive sweating. It is diagnosed either during routine physical examination or evaluation for dilated cardiomyopathy. Occasionally, it is detected during follow up for fetal tachycardia.The majority of sustained tachyarrhythmias in children <1 year were treated with a single anti‐arrhythmic drug or a combination of such drugs depending on the spontaneous regression rate. Although it is more risky in those under 1 year than in other age groups, radiofrequency ablation (RFA) or cryoablation can be applied successfully in a limited number of patients refractory to medical treatment. In this study, we report on sustained tachyarrhythmia patients aged <1 year age in terms of presentation, clinical findings, tachyarrhythmia type, and treatment modality.MethodsThe study was conducted retrospectively in a tertiary cardiac center between November 2010 and November 2016, involving all patients <1 year of age who presented with sustained
