Análise da variabilidade da frequência cardíaca em cordeiros da raça Bergamácia, do nascimento aos 35 dias de idade

Abstract: RESUMOA atividade do sistema nervoso autônomo sobre o coração pode ser verificada pela variabilidade da frequência cardíaca (VFC), método que quantifica e assim infere sobre a modulação autonômica cardíaca, refletindo o funcionamento do sistema nervoso autônomo. Durante o período neonatal, diferenças significativas no que se refere à maturação autonômica são descritas em diversas espécies. Embora a espécie ovina venha sendo utilizada como modelo experimental em diversos protocolos em neonatologia e cardiologia… Show more

“…In relation to HR, no differences were observed among the devices with the predominance of values within the normal range for adult sheep (KUMAR et al, 2007), which suggests the minimization of stress with the method adopted in the evaluation of sheep, as well as the period of the day adopted for the execution of the present study (SZABUNIEWICK;CLARK, 1967). Data regarding the increase in HR in obtaining electrocardiography due to stress and its relationship with neonates up to 35 days of age were described by Chiacchio et al (2018) and Koether et al (2016) Pogliani et al (2013), justified by the stress of contention and chest format. Results that were not observed in the present study, with the HR values obtained remaining stable with a predominance of sympathetic activity (KEUNEN et al, 2000).…”

“…Sheep farming has gained a prominent role in the Brazilian territory due to the increase in farms and its use as a scientific experimental model (KOETHER et al, 2016). According to Lavinsky; Seibel (2001) and Rabbani et al (2008) when they studied the sheep species anatomically, concluded that some anatomical and physiological structures were similar to humans.…”
