Electrocardiographic Studies in Garol Sheep and Black Bengal Goats
Jafrin Ara Ahmed and Sagar Sanyal

Abstract:
The study was attempted to describe the normal electrocardiographic pattern in Garol sheep and black Bengal goats using three bipolar standard limb leads (lead 1, 2 and 3) and three unipolar augmented limb leads (aVR, aVL and aVF). A total of 48 healthy black Bengal goats (Capra hircus) and 14 Garol sheep of both sexes, ranging in age from 1 to 3 years, were used in the study. The heart rate varied from 68 to 150 beats min-1 with a mean of 101±2.6 beats min-1 in goats and 75 to 115 beats min-1 with a mean of 85±2.8 beats min-1 in sheep. In certain cases the P wave in goats could not be measured in the ECG. While 9 goats were found with negative P, one goat showed a notched P wave. The QRS complexes in goat were variable and difficult to classify as a normal pattern. QRS was recorded negative in lead 1 and 2 and positive in lead 3. T waves were recorded to be positive in lead 1 and 2 and negative in lead 3 in goats. In all the experimental sheep, P waves were recorded to be positive and no negative P waves were observed. The QRS complex in sheep was found both monophasic and diphasic in different standard bipolar leads. All T waves were recorded to be negative in three standard bipolar leads in the case of sheep. The electrical cardiac axis in black Bengal goats ranged from -166 to +168°.
