Keywords: Electrocardiogram (ECG), cow, right-sided displacement of the abomasum

This case report describes some parameters of clinical findings and clinical biochemical in five cases of right-sided displacement of the abomasum, with particular interest in paroxymal ventricular tachycardia (PVT) observed in 3 of these cases.

Systemic physical examination of cases as made; their haemotocrit level, total white blood cell, differential white blood cell counts were determined. Cl- in rumen content and K+ Na+, Cl-, inorganic P, Ca++ ve Mg++ levels in blood sera were also measured. Electrocardiograms (ECG) of these cases were taken using base apex (BA) lead system.

Heart rates were above physiological range while rumen contraction was below the normal range in all cases. Rumen pH was within the physiological range while Cl- level was determined above the maximum physiological range in especially four cases.

The finding that serum K+ and Cl- concentrations were below the minimum physiological range indicated that there was a decrease in the levels of afore mentioned parameters in blood.

Sinus tachycardia in twu case and PVT in three cases were associated with metabolic alcolosis resulting from hypochloremia and hypokalemia.

The absence of P wave on ECG of three cases with PVT, greater amplitude waveforms in general, PRa and QTa intervals and shorter time of PRs and STs segments were associated with an increase in the frequency of heart beats of all cases on the other hand, the greater QTc intervals in four cases were thought to be associated with hypocalcemia.
