Left heart catheterization can be a useful diagnostic study to ascertain the severity of the dynamic outflow obstruction and its location. Among patients who have chest discomfort or an anginal equivalent, coronary angiography carries a class I recommendation to evaluate for the presence of obstructive coronary artery disease.The prognostic value of electrophysiologic testing of patients with HOCM in the absence of spontaneous, sustained ventricular tachycardia is limited, and in fact, the study itself may be dangerous.  Paced electrogram fractionation in hypertrophic<unk>  may helpful in determining which patients are at risk for ventricular fibrillation.
