Sudden Cardiac Death and Idiopathic Ventricular Arrhythmias

Ventricular arrhythmias (VAs) in patients without structural heart disease can be found in a significant portion of the general population. The prognosis of patients with idiopathic VA is usually favorable and patients are often asymptomatic. However, sudden cardiac death (SCD) as a consequence of idiopathic VA has been reported. The aim of this review is to present an overview of the association between idiopathic VA and SCD.
