“…In our study, inverted T-wave was very common in Golden Retriever breed (66%) followed by German Shepherd (50%) and less frequent in Labrador (10%). The genesis of T-wave is very complex and the determinants of T-wave polarity were yet to be fully understood [ 21 , 22 ], whereas the altered polarity of T-wave in Lead II may be caused due to elevation of the diaphragm during respiration [ 23 , 24 ].…”

Aim: The present study has been conducted to evaluate the variation in electrocardiogram (ECG) parameters among different trained breeds of dogs (viz. Labrador, German Shepherd, and Golden Retriever) used for security reasons. Materials and Methods: The ECG was recorded by single channel ECG at a paper speed of 25 mm/s and calibration of 10 mm=1 mV. The recordings were taken from all the standard bipolar limb leads (Lead-I, II, and III) and unipolar augmented limb leads (Lead-aVR, aVL, and aVF).

“…Це може бути передумовою для розвитку аритмій (Illarionova, 2012). Згідно з даними Noszczyk-Nowak A. , частота появи патологічних аритмій у загальній популяції собак становить 39,6 %, а за результатими досліджень Kumar A. та Aptekmann K. (Aptekmann et al, 2010;Kumar et al, 2014) -21,9 % та 27,8 % відповідно. Натомість, інцидентність фізіологічних аритмій складає 8,0 % .…”

“…Найпоширенішим видом суправентрикулярних аритмій (СВА) є фібриляція передсердь (ФП), її частка складає 33,7 % від усіх патологічних аритмій . За даними інших авторів (Aptekmann et al, 2010;Kumar et al, 2014), у собак, крім миготливої аритмії, також рівнозначно діагностують синусову тахікардію. Причинами її розвитку вважають (Aptekmann et al, 2010) фізіологічний стан собак -стрес, страх.…”

“…Ряд дослідників у своїх роботах (Kumar et al, 2014; проводили статистичний аналіз поширення аритмій відповідно до віку, статі, ваги, породи. Так, аритмії частіше реєструють у самок (22,98 %) та у тварин 1-3-річного віку, найвищий відносний ризик їхньої появи у собак породи померанський шпіц (1,76) (Kumar et al, 2014). У 65 % самців з віковим діапазоном понад 6 років діагностують суправентрикулярні аритмії.…”

An important pathogenetic link of the progression of chronic heart failure of various genesis is the development of arrhythmias. They significantly complicate the course of CHF, because they lead to decreased cardiac output and increased hypoxia. The aim of our study was to investigate and evaluate the electrical activity of the heart of dogs with CHF. The research was performed on the basis of the private veterinary center “Vetmed” (Lviv) in 2016–2017. The study included 36 dogs of different breeds, ages, sexes with symptoms of chronic heart failure. A standard six-lead electrocardiogram (ECG) was recorded in all dogs in the right lateral position using an electrocardiograph “Vet ECG Ve – 300” (speed 50mm/s, sensitivity of the device 1mV = 10 mm). The obtained data were compared with reference values, and also took into account the variation of individual indicators depending on body weight. According to the results of our study, it was found that the frequency of arrhythmias in dogs with CHF is 75.0 %, of which 8.3 % – life-threatening, 38.9 % of the examined animals needed treatment, and 27.8 % – annual ECG monitoring. The signs of remodeling processes are found in 63.9 % of sick dogs, signs of ischemia – in 25 % and only in 2.8 % of animals – ECG without changes. The structure of arrhythmia in dogs with CHF is dominated by sinus tachycardia (47.2 %), sinus bradycardia (8.3 %), ventricular arrhythmias (5.6 %), atrial fibrillation (5.6 %), ventricular tachycardia (2.8 %). Among conduction disorders, we register intraatrial blockade (13.9 %) and AV-blockade of the first degree (8.3 %). In 13.9 % of animals ECG signs of fibrosis, ischemia are combined with changes in the size of the heart chambers. The results of our study show that a significant number of dogs with CHF have arrhythmias and conduction disorders. In order to improve diagnosis and treatment, the prospect of further research is to establish an association between ECG and echocardiographic changes in dogs with CHF, which can be both a cause of CH and its consequence and a predictor of an unfavorable prognosis.

“…Supraventricular trigeminy has not been reported by retrospective (APTEKMANN et al, 2010) and prospective (VARSHNEY et al, 2013;KUMAR et al, 2014) studies that evaluated cardiac arrhythmias in dogs. In studies evaluating cardiac arrhythmias in dogs with MMVD using conventional and Holter (24 hours) ECG, despite the higher incidence of arrhythmias of supraventricular origin, supraventricular trigeminy is not reported.…”

RESUMO: O trigeminismo supraventricular é um distúrbio incomum de formação do impulso elétrico cardíaco. Detectar e tratar arritmias cardíacas são um importante objetivo terapêutico em cardiologia. O objetivo desta nota é relatar a ocorrência de trigeminismo supraventricular em um cão com doença mixomatosa da valva mitral (DMVM). Um cão sem raça definida, macho, inteiro, 15 anos de idade e 13kg foi levado para avaliação cardíaca com um histórico de sopro cardíaco, tosse, dispneia e ascite. Os achados ecocardiográficos foram compatíveis com doença mixomatosa de valvas mitral e tricúspide com comprometimento hemodinâmico severo. A eletrocardiografia (ECG) revelou arritmia sinusal com presença de complexos supraventriculares prematuros isolados, aos pares e períodos de trigeminismo supraventricular. O trigeminismo supraventricular não é relatado em estudos retrospectivos e prospectivos que avaliaram arritmias cardíacas em um grande número de cães. O presente relato evidencia que o trigeminismo supraventricular pode ocorrer em cães com DMVM e comprometimento hemodinâmico severo, provavelmente relacionado à dilatação atrial. Ainda, reforça a importância da realização do ECG em cães com DMVM, complementando as informações ecocardiográficas e possibilitando uma melhor abordagem terapêutica.
