一、引言从病人心电图中识别各种心律失常是一种图象识别过程。应用数字计算机就可以完成这种识别过程。但是,数字计算机系统目前价格昂贵,难以普及。实际上,用于临床的大多数心脏监护系统都是用模拟电路来识别心律失常的。遗憾的是,这些系统大多数只能报警心动过速和过缓两种轻度的心律失 I. INTRODUCTION It is an image recognition process to identify various arrhythmias from the patient’s ECG. This recognition process can be done using a digital computer. However, digital computer systems are currently expensive and difficult to popularize. In fact, most cardiac monitoring systems used in clinical practice use analog circuits to identify arrhythmias. Unfortunately, most of these systems only report tachycardia and bradycardia in two mild arrhythmias
