导言冠心病监护系统之发展已在急性心肌梗塞(AMI)后心律失常的控制方面取得明显效益,使心肌梗塞的急性期死亡率自30％降至15～20％。然而,心泵衰竭及心源性休克的死亡率却依就无所改善,在目前已有逐步取代心律失常而成为AMI主要死因的趋势。因而“监护”的概念必然要扩大到床边 Introduction The development of a coronary heart disease monitoring system has achieved significant benefits in the control of arrhythmias after acute myocardial infarction (AMI), reducing the acute mortality rate of myocardial infarction from 30% to 15-20%. However, cardiac pump failure and cardiogenic shock mortality has improved uncorrected. At present, there is a trend of gradually replacing arrhythmia and becoming the major cause of AMI. Therefore, the concept of \"guardianship\" must be expanded to the bedside
