Both monopolar and bipolar recordings of human colonic myoelectrical activity have been made on 29 occasions from implanted serosal electrodes attached to either the ascending colon or transverse colon. Visual and computer analysis of the signals were made and the incidences of the two electrical rhythms present in the colon were compared for the two recording techniques, recording sites, and methods of analysis. The percentage incidence of both rhythms was similar for the mono and bipolar recording techniques in both parts of the colon. The incidence of the two rhythms in the transverse colon was approximately twice that recorded in the ascending colon, this being true for both recording techniques and methods of analysis, but neither was detected for more than 50% of the time. It is concluded that the methods of data analysis probably account for the differing incidences of electrical activity in the human colon that have been reported previously.
通过附着于升结肠或横结肠的植入浆膜电极，已对人类结肠肌电活动进行了29次单极和双极记录。对信号进行了视觉和计算机分析，并针对两种记录技术、记录部位和分析方法，比较了结肠中存在的两种电节律的发生率。结肠两个部位的单极和双极记录技术中，两种节律的发生率百分比相似。横结肠中两种节律的发生率约为升结肠记录发生率的两倍，两种记录技术和分析方法均如此，但两种节律均未在超过50%的时间内被检测到。结论是，数据分析方法可能是先前报道的人类结肠电活动发生率差异的原因。
