ELECTROCARDIOGRAPHIC PARAMETERS OF THE SPORT HORSE

A group of 24 sport horses was surveyed for the characteristic elements of the electrocardiograms done before and after a period of 5 months of physical exercises specific to the competition trainings. The sportive performance was positively correlated with the morphology of the ECG waves: the biphasic aspect of wave P, the sS-type aspect of the QRS complex, the monophasic aspect of the T wave. After the training, the average amplitude of P 2 biphasic wave increased by 14.7%, the average duration of the QRS complex increased by 16%, of the S wave increased by 21.8% and of the monophasic T wave increased by 22.2%.
