左心室收缩末期压力与收缩末期容积的比值近年来被认为是衡量左心室收缩功能的一项良好指标。此方面工作的进展如下:GregoryJ.Dember等人对心绞痛病人运动试验前后所做比值曲线表明:收缩末期血压/收缩末期左室容积,当运动后①左心室射血分数增加不到5%的病人,②新出现或增加了左室壁的低运动区域,③运动后左室收缩末容积增加>50%或④增加P/V指数<35%的均作为不正常。经过对照研究以上这四项指标中,以P/V<35%最为敏感,优于左心室射血分数及心电图的不正常,Nivatpmine等人还证实了简单的左心室收缩末期压力和左心室收缩末期容积是
The ratio of left ventricular end-systolic pressure to end-systolic volume has been considered as a good measure of left ventricular systolic function in recent years. The progress of this work is as follows: Gregory J. Dember and others on angina patients exercise test before and after the ratio curve shows: end systolic / end systolic left ventricular volume, after exercise ① left ventricular ejection fraction increased less than 5% of patients , ② new or increased left ventricular wall area of ?? low exercise, ③ post-exercise left ventricular end-systolic volume increased by> 50% or ④ increased P / V index <35% are not as normal. After the control study of these four indicators above, most sensitive to P / V <35%, superior to left ventricular ejection fraction and ECG abnormalities, Nivatpmine, who also confirmed a simple left ventricular end-systolic pressure and left ventricular contraction The final volume is
