晚电位为局部心肌的除极传导延迟的碎裂电波,是产生心室肌的折返性室性心律失常主要因素,是猝死的诱发原因之一。晚电位的检测是预测室速,室颤的有价值方法。检测晚电位75例病人,心血管疾病组晚电位阳性3例,占该组的6.1％,3例晚电位阳性病人全为缺血性心脏病。非心血管疾病组晚电位全部为阴性。
Late potential for the local myocardial depolarization delayed delayed fragmentation is to produce ventricular muscle reentrant ventricular arrhythmia is the main factor is one of the causes of sudden death. Late detection of potential is a valuable method of predicting VT and VF. Detection of late potentials in 75 patients, cardiovascular disease group posterior potential positive in 3 cases, accounting for 6.1% of the group, 3 cases of late-potential positive patients were all ischemic heart disease. The late potentials of non-cardiovascular disease group were all negative.
