Clinical assessment of arrhythmias in tetralogy of Fallot.

As a major success story of an early surgical era, corrective surgery transformed the prognosis of patients born with tetralogy of Fallot. With lifelong care, healthy survival well into adulthood is now the norm, albeit somewhat blemished by long-term sequelae. Arrhythmias are an important source of morbidity and a leading cause of mortality. This succinct review provides a contemporary summary of the prevalence and types of arrhythmias encountered in tetralogy of Fallot, including conduction disorders, atrial and ventricular tachyarrhythmias, and sudden death. Current prognostic markers and existing diagnostic tools are discussed, and available therapeutic options are elaborated.
