In order to facilitate the analysis of 24-hour tape recordings of ECG for rhythm by the AZTEC technique, we have configured a dual-processor system. It samples the ECG signal from a tape playback unit at a rate of 7501.88 Hz, allowing analysis at 30 x real time. An approach to error recognition and containment for the program, which utilizes the sampling of events, is discussed. Steps are taken to reduce errors caused by human sampling of "high risk" regions of the record.
为了便于使用AZTEC技术对24小时心电图磁带记录进行节律分析，我们配置了一个双处理器系统。它以7501.88 Hz的速率从磁带播放单元对心电图信号进行采样，允许进行30倍实时分析。讨论了一种利用事件采样对程序进行错误识别和控制的方法。采取措施减少因人工对记录的“高风险”区域进行采样而导致的错误。
