| 摘 要： | 目的：观察健康中年人运动试验前后舒张功能的变化。方法：使用多普勒彩色超声心动图仪分别测量102名健康中年人静息时、运动试验后15min及60min的E峰最大流速（EPFV）、A峰最大流速（APFV）、EPFV／APFV（EK／A）比值、E峰减速时间（Edt)。结果：健康中年人运动试验后15min及60min EPFV、E／A比值、Edt与静息时相比均明显下降。APFV运动试验前后无差异。运动试验后15min E/A比值比静息时降低0．5以内。结论：健康中年人运动试验后舒张功能存在生理性下降，运动后15min的E／A比值较静息时明显降低，但应＜0．5。

| Abstract: | Objective: To investigate the left ventricular diastolic function in middle-aged healthy subjects after exercise test with doppler echocardiography. Methods: Doppler echocardiography was done to 102 middle-aged subjects at rest and 15 and 60 minutes after exercise test. Results: The EPFV, EPFV/APFV and Edt 15 and 60min after exercise test were significan. Hy decreased as compared with those at rest. There was no difference between APFV 15min after exercise and APFV at rest. However the E/A ratio 15min after exercise was lower than that at rest. The ratio of the 2 values was <0. 5. Conclusions: Left ventricular diastolic function is decreased physiologically after exercise test. However, the ratio of E/A of 15min after exercise to E/A at rest should be less than 0.5. |
