We studied the correlation between coronary vasodilator reserve and the occurrence of syncope and nonsustained ventricular tachycardia in 84 patients with hypertrophic cardiomyopathy. Twenty patients had at least one syncopal episode and 26 had at least one run of nonsustained ventricular tachycardia on the Holter monitor. Baseline and dipyridamole myocardial blood flow and coronary vasodilator reserve were similar in patients with and without arrhythmias. Patients with nonsustained ventricular tachycardia, however, had significantly larger left ventricular end-diastolic (p <.05) and end-systolic (p <.05) diameters.
