Extracellular myoelectric activity from the terminal ileum, cecum, and colonic pelvic flexure was assessed in 4 adult horses. The collection and analysis of myoelectric data involved the development and use of a computer-based system. After collection, the myoelectric signal was digitally filtered to enhance the activity of interest. The smoothed signal was then processed by use of computer programs designed to identify and count spike-burst activity and estimate burst duration. The intense phases of myoelectric complexes also were identified. The propagation of myoelectric spike-burst activity was assessed over 3 electrode sites to identify the propagative patterns of intestinal motility. There was high correlation between the results of computer-based analysis and those of visual analysis. We concluded that the computer provides a fast, accurate, and reliable means of assessing myoelectric activity.
对4匹成年马的回肠末端、盲肠和结肠骨盆弯曲处的细胞外肌电活动进行了评估。肌电数据的收集和分析涉及基于计算机系统的开发和使用。收集后，对肌电信号进行数字滤波以增强感兴趣的活动。然后使用旨在识别和计数尖峰爆发活动并估计爆发持续时间的计算机程序对平滑后的信号进行处理。还识别了肌电复合波的强烈阶段。在3个电极部位评估了肌电尖峰爆发活动的传播，以确定肠道运动的传播模式。基于计算机的分析结果与视觉分析结果之间存在高度相关性。我们得出结论，计算机提供了一种快速、准确且可靠的评估肌电活动的方法。
