Abstract

Sudden cardiac death occurs in approximately 400000 individuals in the USA each year1–4. Most out of hospital resuscitation studies have shown that the majority of patients who have sudden cardiac death have coronary artery disease, a recent or old myocardial infarction and significant left ventricular dysfunction. Although other cardiac entities such as cardiomyopathy, valvular heart disease, acute myocarditis, the idiopathic long QT syndrome and WPW syndromes can result in sudden cardiac death, these entities are present in a much smaller percentage of patients (25%). Out of hospital resuscitation studies have also shown that in the majority of patients sudden cardiac death is due to a malignant ventricular tachycardia (VT) that degenerates into ventricular fibrillation (VF)5–11. Bradycardia seems to be much less often the cause of sudden cardiac death. In recent years significant advances have been made in understanding the substrate of sustained ventricular tachycardia particularly in patients with coronary artery disease12–14.
