Electrocardiographic Studies in Different Age Groups of Nellore Cross-Breed Sheep

Electrocardiography (ECG) is one of the non-invasive, inexpensive diagnostic techniques to detect the spread of the cardiac impulses. The electrocardiographic parameters have the greatest value in recognizing and diagnosing arrhythmias in animals. Different disease conditions lead to changes in the electrolyte balance [1]. The majority of arrhythmias and conduction disturbances can be detected on clinical examination [2]. For the physician, reference values are important to compare the results from diseased animals. Nellore cross-breed sheep is one of the common adapted breeds in the YSR District of Andhra Pradesh and it is the source for meat production which contributes significant economy to the formers (Figure 1). There are several kinds of literatures on electrocardiographic studies in different animals including in ruminants, but there is no previous study regarding the normal ECG parameters at different age groups in the Nellore cross-breed [3,4]. The current study was done to provide ECG values and to evaluate the effects of age on these parameters in this breed. Volume 6 Issue 2 2018
