Standardizing electrocardiographic and arterial pressure parameters in creole horses of the Bogotá Savannah
Background: Cardiovascular parameters may vary between breeds and physiological stages, hindering the cardiovascular evaluation in horses. Objective: Standardize electrocardiographic (ECG) and arterial pressure (AP) parameters in creole horses from the Bogota Savannah. Methods: 100 horses between males and females were evaluated, divided into 4 groups according to the age (n=25): Group 1 (G1), between 6 months and 1 year old; group 2 (G2), between 1 and 4 years old; group 3 (G3), between 4 and 10 years old and group 4 (G4), over 10 years old. Bipolar, unipolar and precordial leads in ECG, as well as systolic AP (SAP), mean AP (MAP), and diastolic AP (DAP) were evaluated in all groups. Results: 99 animals showed sinus rhythm, from which it was observed one female from G2 and G4 that exhibited left fascicles anterior block; a female from G3 had sinus arrhythmia and one female from G2 evidenced 3 premature ventricular complexes. The presence of the unique and positive P wave, the QRS complex QR type and the biphasic T wave, were the most common in all groups. A significant decrease in the cardiac axis was observed in the G1, in comparison with the other groups. The G1 presented a significant increase in heart rate, SAP, MAP and DAP values. Conclusions: Taking into account the environmental conditions and how the investigation was developed, it is possible to admit that, creole horses from the Bogotá savannah differ in their cardiovascular parameters in relation to age.
