127例心血管病之晚电位检测与分析

THE ANALYSIS OF LATE POTENTIALS OF 127 CASES OF CARDIOVASCULAR DISEASE

本文研究结果表明,127例不同类型的心血管病中,晚电位阳性者39例,其中缺血性心脏病组最高,心肌病次之,心肌炎再次之。在缺血性心脏病组中,以急性心肌梗塞最高,占47％,提示晚电位与病理损伤密切相关。同时还发现,在心电图中呈折返型联律者为34例,其晚电位阳性者高达31例,占92％,说明晚电位是形成折返激动的电生理基础。

This paper studied the ventricular late potential (VVLP) of 127 patients with different cardiac vacsular disease.The result showed that VLP of 39 cases were positive.In this study,the positive rate of VLP in ischemic heart disease groups was heigher than that in cardiomyopathy and myocarditis groaps.'In ischemic heart disease groups.the rate of VLP of acute myocardiac infarction was highest (47%).The paper suggested that VLP was closely related with degree of pathological injnry.It also showed that there were receprocal excitation in EEG of 34,cases the positive rate of VLP was 92% (31 cases).This result showed VLP is the electrophysiolOgical basis of forming reciprocal excitation.
