Electrocardiographic changes and changes in cardiac lactate and troponin I levels associated with search and rescue physical activity in military dogs

Rescue and recovery dogs intercalate the activity intensity developed, which also triggers significant metabolic changes in cardiac physiology. Thus, we evaluated the changes that search simulation causes in glucose, lactate, and cardiac troponin I level (cTnI) and the electrocardiographic and heart rate...

Prevalence, risk factors and survival in dogs with myxomatous valve degeneration

The objective of this study was to describe the prevalence, survival time, and risk factors of myxomatous mitral valve disease (MMVD) in dogs by a retrospective observational cohort study design of a Brazilian veterinary center, admitted from 2012 to 2018 (2.585 days). Considering the 105 dog files confi...

Eletrocardiografia computadorizada em cadelas com tumores mamários

Acta sci. vet. (Impr.); 49 (), 2021
The incidence of cancer has increased due to greater longevity of the animals as a consequence of better control of other diseases, improvement of nutrition and good practices in preventive medicine. Malignant tumors can cause paraneoplastic syndrome such as hypercalcemia, anemia, cachexia, among others ...

Electrocardiographic markers of myocardial conduction and repolarization in Boxer dogs

Pesqui. vet. bras; 40 (8), 2020
ABSTRACT: Electrocardiographic markers have been used in people to classify arrhythmogenic risk. The aims of this study were to investigate electrocardiographic markers of conduction and repolarization in Boxers and non-Boxer dogs, and compare such findings between groups. Ten-lead standard electrocardio...

Retrospective study of allometric relationship between heart rate, electrocardiographic parameters and bodyweight in dogs

The allometric relationship between bodyweight (BW) and heart rate (HR) has been described as inversely proportional in domestic species, but that has been refuted. The relationship between HR and electrocardiographic variables is described in literature. However, studies about the variation and influenc...

Influence of body position on the measurement of electrocardiographic waves in healthy dogs

Pesqui. vet. bras; 38 (2), 2018
The agreement between the electrocardiographic waves measured from tracings recorded in right lateral recumbency and several other unusual body positions was assessed. Electrocardiograms were recorded in 160 healthy dogs in right lateral, left lateral, dorsal and sternal recumbencies, as well as in stand...

Vasovagal tonus index in dog with myxomatous mitral valve disease

Pesqui. vet. bras; 37 (10), 2017
The vasovagal tonus index (VVTI) is a useful and assessable index, obtained from standard ECG recordings, that is used to estimate heart rate variability (HRV), and may provide valuable information regarding the likelihood of progression into congestive heart failure (CHF). In this paperwork, we investig...

Physical and electrocardiographic evaluation of horses used for wagon traction

The objective of this research was to evaluate the electrocardiogram (ECG) of horses used for wagon traction and to compare the results with the parameters obtained from inactive horses or horses submitted to a training routine. Fifty-six 3-15-year-old healthy horses (22 females and 34 males) were divide...

Computerized electrocardiogram in agoutis (Dasyprocta prymnolopha Wagler, 1831) anesthetized with ketamine and midazolam

Pesqui. vet. bras; 37 (2), 2017
An electrocardiogram is a test that assesses heart electrical activity and is applied more frequently in the veterinary care of wild animals. The present study aimed to define the electrocardiogram pattern of agoutis (Dasyprocta prymnolopha Wagler, 1831) anesthetized with ketamine and midazolam. Eighteen...

Influência de diferentes protocolos de contenção nosvalores do eletrocardiograma de macacos-da-noite (Aotus azarae infulatus)

Pesqui. vet. bras; 37 (2), 2017
Macacos-da-noite são muito susceptíveis ao estresse e por isso a contenção química ou física deve ser cuidadosamente avaliada antes de qualquer procedimento. Protocolos anestésicos podem alterar alguns parâmetros fisiológicos, sendo o eletrocardiograma (ECG) um exame muito utilizado para avalia...
