Normal GI motility tracing using the WMC shows GE, small bowel transit, and colonic transit are normal. The GE time is indicated
by the abrupt rise in pH. The capsule also records phasic pressure and body temperature. Whole-gut transit time is indicated
by the drop in temperature from body to environmental temperature. Reproduced with permission from Rao SS, Kuo B, McCallum
