动物试验证明,冠脉再灌注常伴有室性心律失常。但临床上,心肌梗塞(MI)开始后的心律失常中有些可能是缺血心肌电不稳定的表现,而不是再灌注的结果。急性心肌梗塞(AMI)57例,于症状开始后4小时内静脉滴注链激酶。溶栓后共21例(37%)发生室性心律失常,其中加速性心室自身节律13例、非持续性室性心动过速(室速)15例,
Animal experiments show that coronary reperfusion often accompanied by ventricular arrhythmias. However, clinically, some of the arrhythmias after the onset of myocardial infarction (MI) may be the result of electrical instability of ischemic myocardium rather than the result of reperfusion. 57 cases of acute myocardial infarction (AMI), intravenous streptokinase within 4 hours after the onset of symptoms. Thrombolysis after a total of 21 cases (37%) occurred ventricular arrhythmia, including 13 cases of accelerated ventricular rhythm, non-sustained ventricular tachycardia (VT) in 15 cases,
