Ventricular arrhythmias range from benign premature ventricular contractions to ventricular fibrillation and can be asymptomatic or have sudden cardiac death as the first manifestation. Sudden cardiac death is a major public health problem, accounting for 50% of all cardiovascular death.1 Although a plurality of sudden cardiac death occurs in the general population with no apparent cardiac risk factors, the risk is greatest in patients with LVEF of less than 30%, clinical heart failure, prior aborted cardiac arrest, or coronary artery disease.2
