The value of myoelectric recording in the gastrointestinal tract has been limited by the difficulty of analyzing the prolonged recordings which are required to demonstrate integrated physiological activity. This problem has been solved by the use of a tape recording system with accelerated replay, originally developed for cardiac monitoring. Rapid replay not only reduces the time required for data retrieval but also increases the frequency of the recorded signals to allow electronic separation of fast and slow wave activity for on-line conversion into digital pulses suitable for computer analysis. The technique is illustrated by the analysis of an imperfect prolonged multichannel recording of cannine gastrointestinal myoelectric activity, demonstrating some of the possibilities for data analysis and error detection inherent in the system.
胃肠道肌电记录的价值一直受到限制，因为分析为证明整合的生理活动而需要的长时间记录存在困难。通过使用最初为心脏监测开发的具有加速重放功能的磁带记录系统，这个问题得到了解决。快速重放不仅减少了数据检索所需的时间，还提高了记录信号的频率，以便电子分离快波和慢波活动，从而在线转换为适合计算机分析的数字脉冲。通过对犬胃肠道肌电活动不完美的长时间多通道记录进行分析来说明该技术，展示了该系统固有的一些数据分析和错误检测的可能性。
