Key result
Electrophysiologic testing identified an explanatory arrhythmia in all 7 symptomatic patients with hypertrophic cardiomyopathy, and guided therapy prevented symptom recurrence over 120 patient-months.

Electrophysiologic testing may identify treatable arrhythmias in symptomatic HCM; leaves open need for controlled trials before broader adoption.
Observational (n=7)
Does electrophysiologic testing and guided antiarrhythmic therapy prevent symptom recurrence in symptomatic patients with hypertrophic cardiomyopathy?
Electrophysiologic testing can successfully identify arrhythmogenic causes of syncope in hypertrophic cardiomyopathy and guide effective prophylactic antiarrhythmic therapy.
Kowey et al. (1984) conducted an observational in Hypertrophic Obstructive Cardiomyopathy (n=7). Electrophysiologic testing and guided antiarrhythmic therapy was evaluated on Identification of an electrophysiologic abnormality explaining symptoms. Electrophysiologic testing identified an explanatory arrhythmia in all 7 symptomatic patients with hypertrophic cardiomyopathy, and guided therapy prevented symptom recurrence over 120 patient-months.
