【摘要】 目的探讨急性心肌梗死(AMI)的心电图QRS波终末变形与预后的关系。方法回顾性分析181例AMI的首份心电图,根据有无QRS波终末变形,将其分为两组,甲组为变形组58例,乙组为无变形组123例。结果甲组的CPK、CPK-MB的峰值、住院死亡率、心功能Killip≥Ⅲ级的发生率、心律失常发生率均明显高于乙组(P<0.05);甲组的左心室射血分数较低(P<0.05)。结论AMI心电图QRS波终末变形与早期预后有密切关系,可作为负性预后的指标之一。更多还原

【Abstract】 Objective: To determine the relationship between terminal QRS distortion and prognostic factors in acute myocardial infarction(AMI).Methods: According to whether the terminal QRS distortion existed(58 cases) or not(123 cases),the initial electrocardiograms of 181cases of AMI were divided into group A and group B respectively.Results: Group A had a higher concentration of peak CPK and CPK-MB,higher incidence of death and Killip class greater than Ⅲ and higher incidence of arrhythmia.Group A had a lower LEVF.Conclusion: The terminal QRS distortion of the initial ECG may have affinity to the early prognosis in AMI,and can be used as one of the factors in predicting the negative prognosis.更多还原
