Figure 1

Elevated systolic longitudinal velocity in hypertrophic cardiomyopathy (HCM) denotes hyperdynamic function and reduced velocity in patient with dilated cardiomyopathy (DCM) indicates systolic dysfunction. Diastolic dysfunction in patients with HCM and DCM is demonstrated by reduced diastolic longitudinal velocities. Delayed relaxation of left ventricle in patient with DCM is noted.
