心尖搏动图对冠心病人特别是心肌梗塞病人的诊断价值,临床上有过许多研究,结果表明,它对判断心肌缺血引起的左心室功能改变,在定性及定量方面都有一定价值。心尖搏动图通常观察的指标有a波时限,a波高度,特别是a波高度与收缩期波幅高度(E—O)比值,PS_2/S_1P比值(P点为收缩波下降支与收缩波平段接合点)以及波形异常等。但许多报告表明,a/E—O比值的阳性率较低,而PS_2/S_1P比值常难以准确测定,因P点位置常不清楚。本文对心尖搏动图一个新指标——缓慢充盈期(Slow Filling period,SFP)与快速 Apical beating chart on coronary heart disease, especially in patients with myocardial infarction diagnostic value, there have been many clinical studies, the results show that it is to determine myocardial ischemia caused by changes in left ventricular function, in qualitative and quantitative aspects of a certain value. Usually observed apex beat beats the a-wave time limit, a wave height, especially a wave height and systolic amplitude (E-O) ratio, PS2 / S_1P ratio (P point contracting wave descending branch and contracting wave flat junction Point) and abnormal waveforms. However, many reports indicate that the positive rate of a / E-O ratio is low, while the ratio of PS_2 / S_1P is often difficult to measure accurately because the location of point P is unclear. In this paper, a new indicator of apical pulsation - Slow Filling Period (SFP) and rapid
