A new method for studies of circadian rhythm of the bowel evacuatory function in humans is proposed: chronoenterography. The existence of optimal and pessimal phases in the circadian rhythm of enteral evacuatory activity was proven using this method. The optimal phase is associated with 3-4-fold reduced chronorisk of enteral arrhythmia. A new classification of enteral arrhythmia and its stages and severity is proposed.
circadian rhythm - optimal and pessimal phase - chronorisk - enteral arrhythmia
