RESUMONeste estudo, investigaram-se as modificações fisiológicas em Spilotes pullatus, como determinantes das respostas ao medo, obtidas pela exposição ao eletrocardiograma. Foram utilizadas quatro serpentes com média de peso de 0,5±0,06kg. Dois minutos após a fixação dos eletrodos, as serpentes apresentavam-se imóveis, com redução significativa na freqüência cardíaca e aumento nos intervalos PQ, QRS, RR e RT (P<0,05). Os resultados sugerem que a presença de sintomas de medo pode gerar riscos à saúde desses animais.Palavras-chave: serpente, caninana, bradicardia, eletrocardiograma, medo
ABSTRACTThis study investigated electrocardiographic changes in Spilotes pullatus using four snakes weighing 0.5±0.06kg. Two minutes after that electrocardiogram apparatus had been fixed in Spilotes pullatus, snakes were immobile and there was a significant reduction of the heart rate and an increase in PQ, QRS, RR, and RT intervals (P<0.05). Results suggest that the presence of fear symptoms may represent a risk to the health of snakes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
