Abstract: The agouti is a species intensively hunted throughout the Amazon and the semi-arid regions of northeastern Brazil. Considering the current trend in conservation management of wild species, the aim of this study was to determine the morphometric reference to the heart of agouti raised in captivity, based on thoracic and cardiac measurements in these animals. Thirty adult agoutis, 1 to 3 years of age, without clinical signs of cardiac disease were selected. The animals were physically restrained and radiographie… Show more

“…The P wave presented morphology and values, both in duration and in amplitude, very close to the parameters found for animals of the same species not anesthetized [7]. The amplitude of this wave showed no difference between the genders, whereas the duration showed statistical difference.…”

“…The values found for heart rate (HR) of anesthetized agoutis with Ketamine and Xylazine (113.25 ± 29.40 bpm for males and 124.60 ± 24.32 bpm for females) were lower than those found for this same non-anesthetized species (193.42 ± 25.39 bpm) [7]. These results suggest that such a difference may be related to stress during the physical restraint of nonanesthetized animals, leading to sinus tachycardia [13], or to the cardiovascular effects of Xylazine in sedated animals, which provoke a depression of the vasomotor center, increase of the vagal tone and of the baroreceptors activity, resulting in bradycardia [31,44].…”
