Diagnostic tests used in diagnosis and management
Individuals with no or only minor symptoms are often diagnosed as a result of family screening, detection of a murmur during routine examination, or the identification of an abnormal ECG. Any individual suspected of having HCM should undergo a comprehensive cardiac history and physical examination and an electrocardiogram (ECG). ECG testing is the most sensitive routinely performed diagnostic test for HCM, but the ECG abnormalities are not specific to HCM and should prompt further diagnostic evaluation. Left ventricular hypertrophy is nearly universal in symptomatic patients; however, individuals with localized hypertrophy may present with an entirely normal ECG. Typically, the ECG is deemed abnormal with localized or widespread repolarization changes. Prominent Q waves, particularly in the inferior and lateral leads, reflect septal depolarization of the hypertrophied myopathic tissue and may mimic myocardial infarction. The ECG may show p wave abnormalities indicative of left atrial or biatrial enlargement. Individuals with HCM may also present with dysrhythmias such as atrial fibrillation, supraventricular tachycardias, premature ventricular contractions, or ventricular tachycardia.
Once suspected, hypertrophic cardiomyopathy is diagnosed with an echocardiogram specifically a comprehensive transthoracic echocardiogram with two-dimensional, color Doppler, spectral Doppler, and tissue Doppler imaging. The…
