ABSTRACT
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
