在十二例患慢性非器质性便秘的病人和10例对照人研究了其乙状结肠的肌电活动。所有病人表明,通过整个胃肠道的时间超过96小时,并且通过左结肠或直肠结肠时减慢。用腔内双极吸附电极及末端开口的探子、记录其电和机械活动的变化。在病人组和对照组都记录到两组慢波频率,一组较慢的节律为3次/分和一组较快的节律为6次/分。较慢节律的平均出现频率在 The myoelectric activity of the sigmoid colon was studied in 12 patients with chronic non-organic constipation and 10 controls. All patients showed a passage through the entire gastrointestinal tract for more than 96 hours and slowed down through the left colon or colon. Bipolar electrode with the end of the probe and the open end of the probe, record the changes in electrical and mechanical activity. Two groups of slow wave frequencies were recorded in both patient and control groups, with a slower rhythm of 3 beats per minute and a faster group of rhythms of 6 beats per minute. The average frequency of slower rhythms in the
