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 2 0 1例AMI的首份心电图 ,根据TQRSD与否分为TQRSD(+)和TQRSD(- )两组 ,分析其与肌酸磷酸激酶(CPK)峰值、住院期间的心血管事件、心脏功能与室壁运动异常以及冠状动脉病变的关系。结果 :2 0 1例中TQRSD出现率约 1/ 4,TQRSD(+)组的CPK峰值、Killip分级Ⅲ级以上心功能、住院期间死亡率均高于TQRSD(- )组 ,TQRSD(+)组中以超声心动图评价的左心室射血分数较低而区域性室壁运动障碍出现率较高 ,两组冠状动脉造影的血管病变支数及范围无明显差别。结论 :AMI心电图TQRSD可作为预测负性预后的指标之一
Objective: To investigate the relationship between electrocardiogram (QRS) terminal deformation (TQRSD) and prognosis in acute myocardial infarction (AMI). Methods: The first electrocardiogram of 201 patients with AMI was retrospectively analyzed. According to whether TQRSD and TQRSD or not, TQRSD (+) and TQRSD (-) were used to analyze the relationship between them and the peak value of creatine phosphokinase (CPK) Events, cardiac function and wall motion abnormalities and coronary artery disease. Results: The incidence of TQRSD was about 1/4 in 201 cases. The CPK peak in TQRSD (+) group, cardiac function above grade Ⅲ and above, and in-hospital mortality were higher than those in TQRSD (-) and TQRSD In the assessment of echocardiography lower left ventricular ejection fraction and regional wall motion disorders higher incidence of coronary artery angiography in both groups showed no significant difference in the number and extent of vascular lesions. Conclusion: AMI ECG TQRSD can be used as one of the indicators to predict negative prognosis
