Abstract Normal subjects of both sexes between 20 and 63 years were examined with M‐mode echocardiography. Blood pressure (BP), heart rate (HR), and left ventricular (LV) diastolic and systolic function were measured at rest and at the end of a standardized maximal isometric handgrip test. BP and HR increased about 25%. This increase in cardiac work had no significant influence on LV systolic function. Diastolic function (myocardial relaxation and maximum rate of LV filling), however, improved significantly. Isometric handgrip test is a suitable exercise test in combination with M‐mode echocardiography. Studies on LV function during exercise may improve the sensitivity for detection of mild LV dysfunction.
