Left ventricular (LV) functional parameters such as LV volume, LV ejection fraction, ratio of LV systolic peak-pressure and LV end-sysfolic volume(P/V), ratio of LV pressure changing rate (-dp/dt/+dp/dt), etc. 38 patients were studied.

• 本文在38例患者中测定了左室容积和射血分数、左室收缩期峰压/左室收缩末期容积比值(P/V)及左室压力变化速率比值(-dp/dt/+dp/dt)等常用的几个左室功能参数。
