Abstract(s)
As arritmias ou disritmias são alterações na formação, condução, frequência e/ou regularidade do estímulo elétrico do coração, Segundo estudos recentes, estas alterações podem ser observadas em 2.5% dos cães anestesiados. Quando presentes, aumentam o risco de surgir hipoxia, hipotensão, comprometimento da perfusão de órgãos e até paragem cardíaca.
Os animais com mais de seis anos de idade, assintomáticos ou portadores de sintomatologia cardiorrespiratória/pulmonar devem ser submetidos a avaliação pré-anestésica antes de quaisquer procedimentos.
O objetivo deste estudo foi caracterizar os animais, atendidos pelo Serviço de Cardiologia do Hospital Veterinário da Faculdade de Medicina Veterinária e Zootecnica (FMVZ) da Universidade Estadual Paulista “João de Mesquita Filho” (UNESP) – Campus de Botucatu, que foram selecionados para avaliação cardíaca pré-anestésica. O estudo pretende identificar quais as alterações encontradas, tanto na anamnese e exame físico como no exame eletrocardiográfico.
Foram analisadas várias variáveis demográficas e clínicas, da amostra em estudo, e a sua influência na eletrocardiografia. Os dados foram analisados através do software R® para testes paramétricos (análise descritiva, análise de variância, T test, Tukey post hoc test e teste de Qui-quadrado).
Concluiu-se que 64.8% dos animais geriátricos que apresentaram alterações eletrocardiográficas eram assintomáticos. Concluiu-se também que o aumento da duração da onda P e do complexo QRS foram as alterações mais frequentemente observadas, em 70.5% e 69.3% dos animais em estudo respetivamente.
Este estudo mostra a necessidade de ser realizada uma avaliação pré-anestésica completa a animais geriátricos, sendo ou não portadores de patologia cardíaca previamente diagnosticada.
Arrhythmias or dysrhythmias are disorders in the formation, conduction, frequency and /or regularity of the electrical stimulus of the heart. According to recent studies, these changes were observed in 2.5% of anesthetized dogs. When present, they may increase the risk of hypoxia, hypotension, impairment of organ perfusion, and even cardiac arrest. Animals over six years of age, asymptomatic or with cardiorespiratory/pulmonary symptoms should undergo preanesthetic evaluation before any procedures. The objective of this study was to characterize the animals assisted by the Cardiology Service of the Veterinary Hospital of the Veterinary Medicine and Zootechnical School of the “João de Mesquita e Filho” State University – Botucatu Campus, which were selected for preanesthetic cardiac evaluation. It aims to identify the alterations found, both in anamnesis and physical examination and in the electrocardiographic exam. Several demographic and clinical parameters were assessed in order to study its influence on eletrocardiography. Data was analyzed through R® software for parametric tests (descriptive analysis, analysis of variance, T test, Tukey post hoc test and chi-square test). The present study showed that 64.8% of the geriatric animals were asymptomatic. The increase in the duration of the P wave and in the QRS complex were the most frequently observed alterations, in 70.5% and 69.3%, respectively. This study emphasizes the need to carry out a complete pre-anesthetic evaluation to geriatric animals, whether or not they have been previously diagnosed with heart disease.
