76例急性心肌梗塞患者出院前的动态心电图分析

Dynamic EKG Analyses in 76 Patients with Acute Myocardial Infarction before Leaving Hospital

对76例急性心肌梗塞患者于出院前进行24小时动态心电图分析,结果检出心律失常64例次,完全无心律失常23例。检出 ST 段改变53例,其中无症状心肌缺血44例(83.02%),有症状9例(16.98%)。单纯 T 波倒置呈冠状 T14例,24小时内完全无 ST-T 改变9例。其中13例动态心电图与冠状动脉造影对比,两项结果均为阳性11例,2例动态心电图无 ST-T 改变而冠状动脉造影证实有多支病变。动态心电图对急性心肌梗塞患者出院前心律失常、ST-T 改变的检出以及对预后判断有重要临床价值,也可作为一项长期随访手段。

The results of 24 hour ambulatory monitoring EKG in 76 patients with acute myo-cardial infarction(AMI)were analysed.Arrhythmia was detected in 64 cases.Twenty-three had no arrhythmia.ST segment changes were found in 53 cases,among whom44 cases had asymptomatic myocardial ischemia(88.02%)and 9 cases had symptomaticmyocardial ischemia(16.98%).Fourteen cases had only inverted T wave like coronaryT wave.Nine cases had no any ST-T changes.A correlation between dynamic EKG and coronary arteriography was observed in 13 cases.In 11 cases both the two resultswere positive.In 2 cases dynamic EKG showed no ischemia while coronary arteriog-raphy showed multivessel disease.Arrhythmia and ST-T changes detected by dynamicEKG in patients with AMI before leaving hospital had important clinical significance.Dynamic EKG may be a useful indicator for long-term follow-up and provide reliablereference.
