60年代以来,由于电子仪器迅速发展,国际上开始对冠心病急性心肌梗塞发生的心律失常进行了监测,尤其是监测可导致猝死的高危险性室性心律失常取得了显著效果。由于早期发现及治疗,使急性心肌梗塞患者的病死率由40～50%下降至10～20%。为使冠心病的病死率进一步下降,又对心源性休克、心力衰竭及其它合并症等进行了血流动力学监测。它不仅 Since the 1960s, due to the rapid development of electronic instruments, the international community has started to monitor the occurrence of arrhythmias in patients with coronary heart disease and acute myocardial infarction. In particular, the monitoring of high-risk ventricular arrhythmias that cause sudden death has achieved remarkable results. Due to early detection and treatment, the mortality of patients with acute myocardial infarction decreased from 40 to 50% to 10 to 20%. To further reduce the mortality of coronary heart disease, but also on cardiogenic shock, heart failure and other complications of hemodynamic monitoring. It is not only
