Basic electrical rhythm frequency decreased from approximately 16.4 to 8.3 cpm after 25 minutes of ischemia. Reperfusion of ischemic bowel resulted in recovery of ECA frequency to approximately 14.3 cpm 10 minutes after blood flow was restored. Figure 1 below shows the comparision of electrical and magnetic data. Decreasing ECA frequency can be seen in both sets of data. Figure 2 below graphically shows the mean magnetic and electrical ECA frequency plotted together with the control for each time period during the study.
Error bars correspond to the standard error of the mean.
Asterisks indicate ischemia values significantly different from baseline. The control ECA frequency did not decrease with time after superior mesenteric artery occlusion.
