摘要
目的:研究心室晚电位(LP)与梗塞部位、恶性室性心律失常和心功能的关系,以及LP对心肌梗塞(MI)后发生室性心动过速/心室颤动(VT/VF)和猝死的预测作用。方法:用晚电位记录仪对168例MI患者进行检测和随访分析。结果:本组MI患者中LP的阳性检出率为27%,多壁MI组LP阳性率明显高于前(间)壁MI组(P<005),VT/VF和猝死患者的LP阳性率明显高于无VT/VF患者(P<001),MI伴心功能不全者LP阳性率明显高于有MI但心功能Ⅰ级者(P<001)。结论:LP与MI范围的大小、心脏的功能状态以及VT/VF或猝死有密切关系。
Objective:To study the relationship of ventricular late potentials(LP)to the site of myocardial infarction(MI),malignant ventricular arrhythmias and cardiac functions;and the value of LP in predicting the occurrence of ventricular tachycardia/ventricular fibrillation(VT/VF) or sudden death after MI.Methods:The LP was detected by the instrument with signal averaged technique in 168 patients with MI.Results:The positive rate of LP was 27% in all patients with MI with a significant difference between the multi wall MI group and the anterior(septal)wall MI group( P <0 05),between the patients with VT/VF and sudden death and these without VT/VF( P <0 01),and between the MI patients with cardiac dysfunction and these without dysfunction( P <0 01),Conclusion:There are close relations on LP to the extent of MI,cardiac function and VT/VF or sudden death.However,the patients with old MI who underwent sudden death seems not to be related with LP.
