本文报道54例正常人和51例冠心病人二维超声心动图食管起搏负荷试验的结果.起搏前和起搏中分别测定了左室功能的变化,并用电子计算机多因素判别分析法做综合分析。将起搏前和起搏中的敏感指标分别引入方程,建立了三个诊断用的判别函数式。各判别函数式对冠心病诊断的敏感性分别达74.51%,90.20%,和93.33%,明显地高于起搏心电图(66.67%).
This paper reports the results of two-dimensional echocardiographic esophageal pacing stress test in 54 normal subjects and 51 patients with coronary heart disease.The changes of left ventricular function were measured before pacing and pacing respectively.Multiple factor discriminant analysis Comprehensive analysis. Sensitive indices before pacing and pacing were introduced into the equations respectively, and three discriminant functions for diagnosis were established. The diagnostic sensitivity of each discriminant function to coronary heart disease was 74.51%, 90.20% and 93.33% respectively, which was significantly higher than that of pacing electrocardiogram (66.67%).
