A 15 year old youth, who presented with out-of-hospital cardiac arrest due to documented ventricular fibrillation, was found to have nonobstructive hypertrophic cardiomyopathy. Electrophysiologic study demonstrated inducible sustained atrial fibrillation with a rapid ventricular response. This rhythm, associated with hypotension and evidence of myocardial ischemia, spontaneously degenerated into ventricular fibrillation. No ventricular arrhythmias were inducible by programmed ventricular stimulation. Therapy with metoprolol and verapamil slowed the ventricular rate during atrial fibrillation and maintained hemodynamic stability, both during followup electrophysiologic study and during a subsequent spontaneous episode.
