Abstract
Horses and ponies have physiological peculiarities in their cardiovascular system in comparison with other species as well as among themselves. Electrocardiogram (ECG) studies in ponies help to elucidate the peculiarities of cardiovascular system functioning, to establish reference values for parameters and to perform early diagnosis of arrhythmias. Arrhythmias, or irregular heart rhythms, can significantly affect the health of horses. Regular ECG screening can help detect early signs of cardiovascular disease such as myocarditis, valvular disease and congenital heart defects. Since horses and ponies come in different breeds, each with unique cardiovascular characteristics, this study aims to establish normative electrocardiogram parameters for ponies to allow for more accurate interpretation of electrocardiographic data. The study involved 18 ponies, aged 4–9 years, in a relatively calm state. Nine animals formed the control group and nine with signs of obesity formed the study group. All animals underwent a general clinical examination using widely accepted methods. Electrocardiographic studies were performed using the BeeW recorder, a state-of-the-art miniature electrocardiograph that allows registration, analysis and interpretation of electrocardiograms over the Internet using an Android tablet, smartphone or laptop. The study showed that the average heart rate (HR) for all ponies was 44.6 ± 2.1 bpm. No cases of sinus bradycardia with HR below 24 bpm were observed. Thirteen animals (72.2%) had HR in the range of 24–42 bpm, while five animals (27.8%) had sinus tachycardia. ECG findings showed positive P waves in 10 animals (55.5%) and negative P waves in 8 (44.5%). Positive T waves were observed in 5 animals (27.8%), while 13 (72.2%) had negative T waves. The QRS complex was predominantly a qR pattern with variations including QR, Qr, and qRS. In addition, two animals had sinus tachycardia and two had atrioventricular block
