自从1978年 Barbari 等首先从体表检测心室晚电位(LP)以来,国内外对此进行了大量研究,笔者根据自己的体会结合文献对信息叠加心电图(SA-ECG)记录 LP 的研究进展作一综述。一.LP 的病理基础 1961年 Durrer等首先在研究实验犬缺血心肌兴奋过程中,发现心内膜下梗塞区的相应心外膜区有延迟电位存在,认为它是该区兴奋延迟所致。整个心肌传导速度取决于激动过程是否同步和心肌纤维的反应性,缓慢非同
Since 1978, Barbari and other ventricular late potentials (LP) first detected from the body surface, a lot of research at home and abroad, the author based on their own experience combined with the literature on the information superimposed electrocardiogram (SA-ECG) recorded LP for a Summary. A pathological basis of LP Durrer et al. First in the study of experimental canine ischemic myocardium excited process, found in the subependymal infarct area of the corresponding epicardial area there is a delay potential, that it is caused by the excitement of the excitement in the area. The entire myocardial conduction velocity depends on whether the activation process is synchronous and the reactivity of myocardial fibers,
