“…Such effect can lead to cardiac dysfunction and the development of DCM, which is manifested by supraventricular and ventricular arrhythmias, myocardial failure, or both, similar to what was observed in dogs from group B, which was previously described by Kehoe (1978), Mauldin et al (1992), Jacobs (1996), Kittleson (1998), Andrade (2002), Souza (2004) and Silva and Camacho, 2005. Electrocardiographic monitoring for 24 hours allowed a continuous recording of the cardiac electrical activity, which made possible a better verification of the occurrence of arrhythmias. Sometimes they were transient in dogs suffering doxorubicin-induced cardiomyopathy.…”

Early identification of arrhythmias in dogs showing doxorubicin-induced cardiomyopathy was studied. Ten healthy dogs were assigned to groups A (n=5) and B (n=5). Dogs from group B were given doxorubicin 30mg/m 2 intravenously, every 21 days, until a cumulative dose of 180mg/m 2 or 240mg/m 2 was reached. Dogs from group A (used as control) were administered saline intravenously at the same group B intervals. As soon as myocardium dysfunction was observed in dogs from group B, determined by a shortening fraction below 20%, increased E-point to septal separation above 0.7cm, and increased end-systolic left ventricular volume index (61.4ml/m 2 ), a 24-hour Holter was recorded in all dogs from both groups. There was an increase of minimum heart rate (44.6%) and mean heart rate (41.7%) in animals from group B in comparison with the control animals. Either supraventricular or ventricular arrhythmias were observed, despite group B dogs showed higher occurrence of supraventricular arrhytmias. Holter monitoring is efficient in early determination of heart rate and cardiac rhythm alterations in dogs showing doxorubicin-induced myocardial dysfunction.Keywords: dog, doxorubicin, eletrocardiogram, cardiopathy RESUMO O estudo consistiu na identificação precoce da ocorrência de arritmias em cães com cardiomiopatia dilatada experimental induzida pela doxorrubicina (DOX). Utilizaram-se 10 cães adultos, sadios, distribuídos nos grupos A (n=5) e B (n=5

“…It is also possible to occur ventricular arrhythmias, intraventricular conduction disturbances and sinus tachycardia (Kehoe et al, 1978;Susaneck, 1983;Cowan and Jacobs, 1990;Crystal and Rush, 1991;Mauldin et al, 1992;Jacobs, 1996;Andrade, 2002;Silva and Camacho, 2005).…”

“…With advances in information technology, the computerized electrocardiogram has been used in human medicine as an auxiliary diagnostic method and is currently used increasingly in veterinary medicine (Tilley 1981, Andrade et al 2004, Aptekmann et al 2010, Neto et al 2010, Gava et al 2011. According to Tilley (1992), in veterinary medicine, the computerized ECG improved the quality of emergency electrocardiogram services and other advantages including a decrease in the time needed to carry out the exam.…”

Pesq. Vet. Bras. 33(Supl.1):8-14, dezembro 2013 8 RESUMO.-[Avaliação do eletrocardiograma em cutias (Dasyprocta primnolopha, Wagler 1831) não-anestesiadas clinicamente saudáveis.] A cutia é uma das espé-cies mais intensamente caçados em toda a Amazônia e as regiões semi-áridas do nordeste do Brasil. Considerando--se a tendência atual no manejo de animais silvestres em cativeiro, o objetivo deste estudo foi determinar os valores de referência para o coração cutia criadas em cativeiro, com base em avaliações do eletrocardiograma (ECG). Foram selecionadas cutias adultas e sem sinais clínicos de doença cardíaca (n=30). Os animais foram contidos fisicamente e, em seguida, o ECG foi realizado. Medições padronizadas foram tomadas para estabelecer a análise estatística dos dados. Análise do complexo QRS apresentou valores compatíveis com os relatórios pregressos em animais animais de companhia, assim como para os poucos dados disponí-veis para outras espécies selvagens e exóticas, com exceção da onda T, que mostrou amplitude semelhante à onda R em The agouti is one of the most intensely hunted species throughout the Amazon and the semiarid regions of north-eastern Brazil. Considering the current tendency of wild animal management in captivity, the objective of this study was to determine heart reference values for agouti raised in captivity, based on electrocardiographic assessments (ECG). Adult agouti were selected without clinical signs of heart disease (n=30). The animals were restrained physically and then the ECG was performed. Standardized measurements were taken to establish the statistical analysis of the data. Analysis of the QRS complex showed values compatible with previous reports in peer animals and the limited data available for other wild and exotic species, except for the T wave that showed similar amplitude to the R wave in all the animals studied. The data obtained provided the first reference values for ECG tracings in agouti, contributing to a better understanding of heart electrophysiology in identifying myocardial pathology in these animals. Electrocardiogram assessment in non-anaesthetized clinically healthy agouti (Dasyprocta primnolopha, Wagler 1831) todos os animais estudados. Os dados obtidos permitiram a aquisição dos primeiros valores de referência para os traçados de ECG em cutias, contribuindo para uma melhor compreensão eletrofisiologia cardíaca, na identificação de miocardiopatia nesses animais.
