“…Electrocardiography (ECG) is the test of choice for confirming the diagnosis of heart rhythm disturbances. A base‐apex (rhythm strip) ECG is usually sufficient, but additional surface leads, intracardiac leads, or transesophageal leads are needed to better evaluate the ECG waveforms in some cases. A portable ECG unit is useful in the field for documenting arrhythmias.…”

Murmurs and arrhythmias are commonly detected in equine athletes. Assessing the relevance of these cardiovascular abnormalities in the performance horse can be challenging. Determining the impact of a cardiovascular disorder on performance, life expectancy, horse and rider or driver safety relative to the owner's future expectations is paramount. A comprehensive assessment of the cardiovascular abnormality detected is essential to determine its severity and achieve these aims. This consensus statement presents a general approach to the assessment of cardiovascular abnormalities, followed by a discussion of the common murmurs and arrhythmias. The description, diagnosis, evaluation, and prognosis are considered for each cardiovascular abnormality. The recommendations presented herein are based on available literature and a consensus of the panelists. While the majority of horses with cardiovascular abnormalities have a useful performance life, periodic reexaminations are indicated for those with clinically relevant cardiovascular disease. Horses with pulmonary hypertension, CHF, or complex ventricular arrhythmias should not be ridden or driven.

“…The significance of the ECG findings was interpreted in light of the clinical signs shown by affected horses. An ECG can make a definitive diagnosis if an arrhythmia is suspected during cardiac auscultation [38,39]. The arrhythmia reported in this study may be due to myocardial infarction, a condition reported in experimental Trypanosoma brucei infection in dogs [10].…”

HE objective of this study is to evaluate the electrocardiographic findings in naturally infected horses by trypanosomiasis as well as to investigate the presence of Trypanosoma sp. in northern Iraq. Twenty-two male horses aged 3-7 years and their weights of 340 to 390 kg were examined. All infected horses showed anaemia, also two horses died, with clinical signs suggestive of heart failure. Results showed trypanosomes in blood smears of infected horses, which was confirmed using the conventional polymerase chain reaction (c-PCR) technique. 12 horses (54.54%) are infected of them 7 (31.82%) were infected with T. evansi and 5 (22.72%) were infected with T. vivax. Clinical, haematological, and electrocardiographic evaluations (ECG) were performed. Serum cardiac troponin (cTnI) biomarker was measured to support ECG findings and a deeper understanding of myocardial tissue damage, and the results were compared with normal values in healthy horses and were found negative for blood smear and PCR. The electrocardiograms showed significant changes which characterized by the length of the P and T waves and the QRS complex in addition to the deviation of the electrical heart axis to the left and tachycardia. The mean values of serum cTnI were significantly higher in T. evansi and T. vivax of infected horses (0.78 and 17.5 ng/m respectively) compared to healthy horses (0.01 range 0.01-0.03 ng/mL). T. evansi and T. vivax are responsible for the incidence of heart lesions, which are associated with heart failure, changes in the electrocardiogram, and death of the affected horses.

“…Alterações no ritmo cardíaco são relatadas com frequência nos equinos (Fernandes, et al, 2004;Verheyen, et al, 2010;Sleeper, 2017) indicando a suscetibilidade desta espécie para ocorrência de arritmias cardíacas (Buhl, et al, 2010). Entretanto, muitas alterações são detectadas independentemente de doença ou alteração funcional do coração, sendo atribuídas à alta variação do tônus vagal em condições de repouso e, consideradas benignas ou fisiológicas (Verheyen, et al, 2010). Elas devem, no entanto, ser diferenciadas de condições 1890 ms 1310 ms patológicas (Miller, 1984), tais como fibrilação atrial, bloqueio atrioventricular (BAV) de terceiro grau e extra-sístoles atrial e ventricular (Buhl, et al, 2010).…”

O objetivo deste estudo foi correlacionar a importância de arritmias em cavalos de corrida Puro Sangue Inglês com baixo desempenho. Foram avaliados 16 equinos (10 machos e 6 fêmeas), com idade entre 2 e 6 anos e pesando 474,5 ± 39,4kg. Estes foram selecionados de acordo com a ocorrência ou não de baixo desempenho, em grupos: grupo baixo desempenho (BD) e grupo controle (CTL). Procedeu-se ao exame eletrocardiográfico contínuo (Holter), sendo avaliados em repouso e em exercício, padronizado para todos. Foram observadas arritmias em ambos os grupos, classificadas como bloqueio atrioventricular de segundo grau (BAV2), bloqueio sinusal (BS), complexo pré-ventricular prematuro (CPVP), complexo ventricular prematuro (CVP) e taquicardia ventricular (TV). BAV2 foi a arritmia mais frequente com média de 1,91 BAV2/h no grupo BD e 3,8 BAV2/h no grupo CTL. Quanto a ocorrência de BS, a média foi 0,76 BS/h no grupo BD e 0,72 BS/h no grupo CTL. Complexo pré-ventricular prematuro obteve média 0,12 CPVP/h no grupo CTL e 0,21 CPVP/h no grupo BD. A comparação de ocorrência de BAV2, BS, CPVP e DVP em ambos os grupos, não obteve diferença estatística significativa. Os resultados sugerem que não houve influência dessas arritmias no baixo desempenho dos animais avaliados.

Abstract: The procedure is promising for diagnosis of supraventricular tachydysrhythmias and might be used in electrophysiological studies and for cardiac pacing.
