Abstract

It has been reported that 75% of the patients dying of sudden cardiac death (SCD) have coronary heart disease. The rhythm most often recorded at the time of sudden cardiac arrest is ventricular fibrillation. No antiarrhythmic agent has clearly been demonstrated to reduce total and SCD mortality in patients at risk for SCD. Implantable cardioverter-defibrillator (ICD) therapy, compared with conventional or traditional antiarrhythmic drug therapy, has been associated with mortality reductions from 23% to 55%, depending on the risk group participating in the trial. The improvement in survival with ICD therapy is almost exclusively due to a reduction in SCD. We reported here on a syncope patient with a history of previous myocardial infarction. The cardiac electrophysiology study revealed sustained ventricular tachycardia and fibrillation presented with loss of consciousness.
