Summary. 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
Keywords: arrhythmia, sinus
tachycardia, atrioventricular block
