Abstract: Routine electrocardiogram in a middle-aged man with left ventricular hypertrophy showed sinus rhythm, a short PR interval, and delta wave, confirming ventricular pre-excitation. Pre-excitation was fixed after a premature atrial complex and in atrial fibrillation, features diagnostic of a fasciculo-ventricular pathway. Genetic testing confirmed a diagnosis of hypertrophic cardiomyopathy.
