摘要
以心阻抗图法对52例冠心病人进行心房收缩时间间期(ASTI)的测量,并与100例同龄组正常人对比,结果表明:冠心病人心房射血前时间缩短(P<0.01),心房射血时间延长(P<0.01),二者比值下降(P<0.01)。ASTI 对于无创性评定冠心病人心室舒张期顺应性改变是一种简单有效的新方法。
Atrial systolic time intervals(ASTI)were measured in 52 coronary artery disease and 100 nor- mal human subjects by using cardiac impedance plethysmography,The results showed that atrial preo- jection period(APEP)shtortened(P<0.01),artrial ejection time(AET)prolonged(P<0.01), and the ratio of the values(APEP/AET)decreased(P<0.01).The results indicate that ASTI mea- sured by cardiac impedance plethysmography is simple and effective in detecting ventricular diastolic compliance in coronary artery disease.
