Echocardiographic evaluation of patients with undocumented arrhythmias occurring in adults late after repair of tetralogy of Fallot

摘要

Aims Arrhythmias occurring late after repair of tetralogy of Fallot (ToF) are common. Due to the risk of sudden cardiac death, attention is focused towards ventricular tachycardias (VT). The aims of this study were to determine the clinical profile of patients with known benign and malignant arrhythmias and to assess patients with palpitations without documented arrhythmias.
