本文通过对50例AMI住院患者心脏负荷试验检查诱发的无症状心肌缺血(SMI)的研究.1 临床资料50例AMI住院患者,男43例,女7例,平均年龄58.3±10.22岁.其中前壁AMI28例,下后壁AMI22例.取患者病初心电图(EKG)观察有无非梗塞导联ST段下移;符合心脏负荷试验检查者(即检查前5～7天内无心功能不全、心绞痛发作及心律失常发生),于AMI发病后 3～4周行蹬车运动试验及/或食道调搏心脏负荷试验,如无阳性结果出现,则至亚极量级运动时心率标准,取出现ST段呈缺血型下移改变且无心绞痛症状发生者进行研究.
In this paper, 50 cases of AMI hospitalized patients with heart stress test-induced asymptomatic myocardial ischemia (SMI) study.1 Clinical data 50 cases of AMI hospitalized patients, 43 males and 7 females, mean age 58.3 ± 10.22 years, of which Anterior AMI in 28 cases and AMI in inferior posterior wall in 22 cases. Take patients with early ECG (EKG) to observe the non-infarction leads ST segment down; in line with the heart load test examiner (ie 5 to 7 days before the examination without heart failure, angina pectoris And arrhythmia), exercise treadmill exercise test and / or esophageal pacing cardiac load 3-4 weeks after onset of AMI, if there is no positive result, then to the sub-maximal exercise heart rate when standard, take the ST segment Was ischemic change down and no angina symptoms were studied.
