摘要
目的 探讨急性心肌梗死(AMI)的心电图QRS波终末变形(TQRSD)与预后的关系。方法 回顾性分析76例AMI的首份心电图,根据有无TQRSD分为TQRSD阳性和TQRSD阴性2组,分析其与肌酸磷酸激酶(CK)峰值、心脏功能及住院期间的心血管事件的关系。结果 TQTSD阳性组的CK峰值、Killp分级Ⅲ级以上心功能、住院期间死亡率及QT离散度(QTd)均高于TQRSD阴性组。另外,TQRSD阳性组中以超声心动图评价的左心室射血分数(LVEF)较TQRSD阴性组低。结论 AMI心电图TQRSD阳性可作为判断预后的指标之一。
Objective To determine the relationship between terminal QRS distortion(TQRSD) and prognostic factors in acute myocardial infarction( AMI). Methods The initial electrocardiogram of 76 cases of AMI were divided into 2 groups according to whether TQRSD + or TQRSD - .The relationship were respectively analysed between TQRSD and peak concentration of CPK, LVEF and cardiovascular events during hospitalization. Results TQRSD ( + ) group was higher in concentration of peak CK, incidence of Killip class greater than Ⅲ , mortality and QT disper-sion(QTd) compared with TQRSD( - ) group. Moreover, TQRSD( + ) group was lower LVEF by echocardiography. Conclusion TQRSD( + ) is one of the factors in predicting the bad prognosis in AM.
