摘　　要：采用脉冲多谱勒超声心动图观察运动中和运动后左室舒张功能的变化。研究结果显示运动时随强度的增加舒张早期最大的峰值速度E峰峰值流速、舒张晚期最大的峰值速度A峰峰值流速,舒张早期最大瞬时压差(PPGE)、舒张末期最大瞬时压差(PPGA)增加,但vE/vA值下降。其动力来源可能与运动时左室的收缩功能提高有关。运动后恢复期E峰、A峰峰值流速,PPGE、PPGA逐渐减少,vE/vA值逐渐增大,并很快恢复到安静状态。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 (v_E/v_A) 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.
