本文探讨急性心肌梗塞后(AMI)后短期内短暂性心肌缺血(TMI)的发生情况及特点。对象及方法:AMI 203例(男152例,女51例),年龄34～76(平均58)岁。以Oxford Medilog 4000——Ⅱ型机行单导联监测。早期(3～15日,平均6.4日)监测201例及晚期(22～93日,平均38日)监测177例,均分别动态监测24小时。患者自行准确记录症状发作及终止时间、活动量。TMI的诊断标准为ST段呈水平型/下斜形压低≥-1.0mm(于J点后80ms处测量)、并持续30秒以上。另外,研究对象中有101例服用过β阻滞剂
This article explores the occurrence and characteristics of transient myocardial ischemia (TMI) after acute myocardial infarction (AMI). Subjects and Methods: There were 203 AMI cases (152 males and 51 females) aged 34-76 (mean 58 years). Take Oxford Medilog 4000 - Ⅱ type machine to monitor the single lead. In the early stage (3 to 15 days, an average of 6.4 days) monitoring of 201 cases and late (22-93 days, an average of 38 days) monitoring of 177 cases, were dynamically monitored for 24 hours. Patients accurately record the onset of symptoms and termination of time, activity. The diagnostic criteria for TMI were ST-segment horizontal / down oblique depression ≥-1.0 mm (measured at 80 ms after point J) for more than 30 seconds. In addition, 101 subjects took beta-blocker
