Abstract
The electrocardiogram (ECG) is an essential component of cardiological examinations in both human and veterinary medicine. The analysis of ECG waveforms is crucial for accurate interpretation. In this study, we analyzed the ECG characteristics of the two most important indigenous horse breeds in Croatia, the Croatian Posavac and the Lipizzaner, comparing the measured values both with each other and with previously published data on ECG waveforms, intervals, and their morphological characteristics in healthy horses. A total of 82 horses were included in the study: 51 Croatian Posavac and 32 Lipizzaners. Electrocardiograms were recorded for five minutes using a base-apex lead, followed by an analysis that included measurements of the duration of the P wave, PR interval, QRS complex, QT interval, and T wave, as well as the amplitudes of the P, Q, R, S, and T waves. The morphological patterns of the P and T waves were recorded separately. This study identified numerous differences between our results and previously published data, as well as statistically significant differences between the studied breeds in the P and T waves and the QRS complex, and additionaly significant sex-based differences were observed. Further research with a larger
sample size is necessary to establish breed-specific reference intervals and to clarify the effects of sex on electrocardiographic parameters.
