一、引言1957年 Holter 提出动态心电监护并发明Holter 式监护仪以来,一直受到医疗界的重视,它对于某些“一过性”心律失常的检出,减少突发病人的死亡,以及对心脏起搏器性能的评价和抗心律失常药物的研究,都有其独特的作用.近年来,由于 CMOS 微处理器的出现和发展,便携式智能化心律失常监护系统也已问世。但由于早期微处理器功能较弱,加之软件 I. INTRODUCTION Since Holter proposed Holter monitor in 1957 and invented the Holter monitor, it has always been valued by the medical profession for the detection of certain “transient” arrhythmias and for the reduction of sudden patient deaths. Pacemaker performance evaluation and anti-arrhythmic drug research, has its unique role.In recent years, due to the emergence and development of CMOS microprocessors, portable intelligent arrhythmia monitoring system has also come out. However, due to the early microprocessor function is weak, combined with software
