Abstract: This study was to evaluate left ventricular diastolic function during exercise and recovery with pulsed Doppler echocardiography. The results show that during exercise with the increasing of exercise intensity the peak transimitral flow velocity in early diastole (peak E),the peak transimitral flow velocity in early diastole (peak A),the peak pressure gradient E (PPGE) and the peak pressure gradient A (PPGA) increased gradually and the atrial filling wave decreased.Increases in left ventricular systolic function with exercise may serve principally to augment these. During recovery the peak E, peak A,PPGE,PPGA and E/A came back to resting values.
Key words:pulsed doppler echocardiography; left ventricular systolic function; left ventricular diastolic function; stead state exercise and recovery
