对27例急性心肌梗塞(AMI)病人于住院即刻,三天、一周、两周、三周、一月以及更长时间检测心室迟电位;心脏收缩时间间期;每搏指数、心指数和心搏功指数。结果显示 AMI 心衰组的心功指标远较非心衰组差,而迟电位的发生率心衰组亦高;下、后壁梗塞组与前壁心梗组的心功能各指标及迟电位阳性率均无统计差异;急性心肌梗塞后心功能各参数随时间推移(经治疗)有好转趋势,而迟电位在不同时间检测都可测到阳性,刚进院时较少,两周左右增多,一个月时最高,且此时心功能参数都有变好的趋势,但好转的心功能参数随着 LP 出现又呈变坏的趋势。故对 AMI 患者的心功能、迟电位最好进行动态监测,不能以一次检查结果为准绳。
Twenty-seven patients with acute myocardial infarction (AMI) were examined for ventricular tachycardia immediately, three days, one week, two weeks, three weeks, one month and longer; systolic time; stroke index, cardiac index and heart Booming index. The results showed that the AMI heart failure group of heart function indicators than non-heart failure group, and the incidence of late potential heart failure group is also high; the posterior wall infarction group and anterior myocardial infarction group heart function indicators and late potentials There was no statistical difference in the positive rate of cardiac function after myocardial infarction. The parameters of cardiac function after AMI showed a trend of improvement with time (treated), while the positive rate of late potentials detected at different time was detectable. , The highest one month, and at this time the heart function parameters have a better trend, but the improved cardiac function parameters with the emergence of LP showed a deteriorating trend. Therefore, patients with AMI cardiac function, the best late dynamic monitoring, can not be a test results as the yardstick.
