The electrocardiographic study was made in 100 healthy showjumping horses, with ages between 4 and 19 year-old, being 61 males and 39 females, with mean bodyweight of 516.3 kg. A mean heart rate of 40.20 ± 13.33 bpm was observed, and the most common cardiac rhythm was sinus rhythm (56%). Alterations in cardiac rhythm were observed in 38% of the animals, as wandering pacemaker (22%), second degree atrioventricular block (4%), first degree atrioventricular block (3%), ventricular premature contraction (2%), atrial premature contraction (1%). There was no relationship between the variables (heart rate, rhythm and arrhythmias) and the athletic performance, age and sex. The heart score data obtained after statistical analysis were not different concerning the athletic performance, age or sex. Therefore, heart score, in this sample, did not appear to be a confident parameter to predict the athletic future or the training level of the individual horse.
