[Computer analysis of colonic myoelectric activity in dogs (author's transl)].
The electric activity of the colon was studied in unanaesthetized dogs equipped with 4 bipolor electrodes in the colon. Computer analysis of signals was made. Recorded electrical activities in the colon were mainly consisted of 2 rhythmic patterns. One was a low frequency rhythm of 3.3 to 6.6 cycles/min and the other was a higher frequency rhythm of 9.2 to 13.4 cycles/min. However, the frequency varied within the two rhythmic patterns in the same portions of the colon.
