急性心肌梗死心电图QRS波终末变形的预后意义

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。

Prognostic significance of terminal QRS distortion in acute myocardial infarction

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.
