52例冠心病患者体表心室晚电位检测

Detection of ventricular late potential in 52 patients with coronary artery disease

目的:探讨冠心病患者心室晚电位(VLP)阳性的临床意义。方法:对52例冠心病患者及61名健康人的心室晚电位进行分析。结果:冠心病组心室晚电位阳性率为28.8%,健康人组为1.6%,两组间晚电位阳性率有显著性差异(P<0.01),尤其心肌梗死的阳性率更高(39.2%)。结论:心室晚电位阳性对预测心脏恶性事件有一定临床价值。

Objective To explore the clinical significance of positive ventricular late potentials（VLP） in patients with coronary artery disease.Method VLP in 52 patients of coronary artery disease and 61 controls were analyzed.Results 28.8% of patients with coronary artery disease had positive VLP,while only 1.6% positive in the control group.There was significant difference between the two groups（P〈0.01）.Furthermore,the positive VLP was more significant in myocardial infarction（39.2%）.Conclusion Positive VLP has a certain clinical value in predicting cardiac malignant events.
