Abstract
Summary Bradycardia was documented in 12 cattle from which food had been withheld for 48 hours in preparation for general anesthesia and an elective surgical procedure. The heart rates decreased by a mean of 14 beats/min, and 4 cows had sinus arrhythmia. To evaluate this finding, the heart rates of 21 clinically normal cattle were evaluated before and after food was withheld for 48 hours. Bradycardia developed in all of the clinically normal cattle, with the mean decrease in heart rate being 23 beats/min. Five of the clinically normal cows developed sinus arrhythmia. It was concluded that bradycardia and sinus arrhythmia in cattle are associated with deprivation of food.This publication has 0 references indexed in Scilit:
