本文研究了121名健康人运动对左室舒末容量的影响。在自行车测功计上完成直立位多级运动试验,运动负荷从200kpm/min开始,每隔2′增加100 kpm,直至筋疲力竭。左室舒末容量是用放射核素~(99m)锝血管造影术获得的。根据运动耐力状况把受试者分成三组。第一组为运动时间≤7.5′,第二组运动时间为7.6—15′,第三组为>15′。这三组的结果均显示左室舒末容量增加和收末容量的减少。第三组的受试者最为年轻,运动时心率最
In this paper, 121 healthy people exercise on left ventricular end-diastolic volume. Perform an upright multi-stage exercise test on a bicycle dynamometer starting at 200kpm / min and increasing 100 kpm every 2 ’until exhausted. Left ventricular end-diastolic volume was obtained using radionuclide ~ (99m) technetium angiography. Subjects were divided into three groups based on exercise endurance status. In the first group, exercise time ≤ 7.5 ’, exercise duration in the second group was 7.6-15’ and in the third group ’> 15’. The results of these three groups showed an increase in left ventricular end-diastolic volume and a decrease in end-cap volume. The third group of subjects were the youngest, exercise most heart rate
