缺血心肌的存活取决于它的氧供量和氧耗量间的平衡。主动脉内囊反搏能改善这种平衡,本工作在山羊身上进行,其体重和心脏大小相当于十来岁儿童的。冠状血管分枝结扎后,心率不齐的出现是一个严重的问题。结扎后半小时间内,对照组(n=34)的心律不齐发生率为56％,七条山羊发展到心室纤颤而死亡。结扎后24小时内其 The survival of ischemic myocardium depends on the balance between oxygen supply and oxygen consumption. Intraaortic balloon pump can improve this balance, the work carried out in goats, their weight and heart size equivalent to the age of ten children. Coronary artery branch ligation, the emergence of irregular heartbeat is a serious problem. Half a hour after ligation, the incidence of arrhythmia in the control group (n = 34) was 56%, and seven goats developed ventricular fibrillation and died. Within 24 hours after ligation it
