Hypertrophic cardiomyopathy (HCM) is a genetic disorder that is characterized by left ventricular hypertrophy unexplained by secondary causes and a nondilated left ventricle with preserved or increased ejection fraction. The diagnosis of hypertrophic cardiomyopathy involves several types of tests. The following are the most important of these.
