对24例急性心肌梗塞(AMI)静脉溶栓治疗后的早期心电图(ECG)进行了动态观察,结果24例冠脉全部再通,其中发生再灌注性心律失常(RA)者22例(占91.7%),均为短暂加速性室性自主心律与频发室性心律失常。当冠脉出现再通后经静滴肝素等 RA 均在12h 内消失。AMI 在静注尿激酶后 ST 段2h内迅速下降50%以上,下壁心梗的 T 波在冠脉再通4～6h 后开始演变,出现酷似陈旧性心肌梗塞图形。
24 cases of acute myocardial infarction (AMI) intravenous thrombolytic therapy after the early electrocardiogram (ECG) were observed, the results of 24 cases of all coronary recanalization, including reperfusion arrhythmia (RA) in 22 cases (91.7 %), Are transient acceleration of ventricular autonomy and frequent ventricular arrhythmias. When the coronary recanalization after intravenous infusion of heparin and other RA were disappeared within 12h. AMI in intravenous injection of urokinase ST segment 2h rapidly decreased more than 50%, inferior myocardial infarction T wave in the coronary recanalization after 4 ~ 6h began to evolve, exactly like the old myocardial infarction pattern.
