Evaluation and treatment of survivors of sudden cardiac death or nonbradycardic syncope unrelated to coronary artery disease.

The authors describe their clinical strategy and experience with electrophysiologic testing in a group of patients who have had at least one episode of sudden cardiac death or nonbradycardic syncope in the absence of coronary artery disease. Their study shows that for this population programmed stimulation commonly induces ventricular tachycardia, which can then be suppressed by drug therapy.
