1.绪言近年来,随着电子计算机的小型化,计算程序有必要简化。本文报导把波形识别子程序化并把这些子程序组合起来认别波形的方法。 2.波形识别法如图1所示,心电图由三个通道同时输入(每序列3.5秒),A/D变换每秒250次,精度10bit。用7点加重移动平均法滤波,在终端机取任一胸导心电图,经过模拟处理形成QRS波的同步信号,转移到A/D变换后的数据中以检出QRS波。在QRS波转移的基础上,根据前后的RR间期识别整拍或不整拍。整拍时,进行心电图各波的测量;不
1. Introduction In recent years, with the miniaturization of electronic computers, computational procedures need to be simplified. This article reports on the waveform recognition subroutine and the subroutines combined to identify the waveform method. 2. Waveform Recognition Method As shown in Figure 1, the ECG is input simultaneously by three channels (3.5 seconds per sequence), A / D conversion is 250 times per second, and the accuracy is 10 bits. With 7-point weighted moving average filtering, the terminal take any chest X-ray ECG, after the formation of the QRS wave analog processing synchronization signal, transferred to the A / D converted data to detect QRS wave. On the basis of the QRS wave transfer, the whole or the whole shot is identified according to the RR interval before and after. When the whole film is taken, the measurement of each wave of the electrocardiogram is performed;
