Acompanhamento eletrocardiográfico no desenvolvimento de ratos Wistar

Abstract: RESUMOA atividade elétrica cardíaca pode ser registrada por meio do eletrocardiograma (ECG), registro capaz de captar as alterações do percurso elétrico. Na literatura científica, não existe descrição de padrões eletrocardiográficos de ratos Wistar desde a fase de recém-nascidos até serem considerados envelhecidos. O objetivo do presente estudo foi avaliar o padrão eletrocardiográfico de ratos Wistar desde a fase de recém-nascidos até serem considerados envelhecidos, no intuito de que os resultados possam cont… Show more

“…If we consider that the average HR value with the range reported in telemetry studies involving male rats is our desired reference value, then a slightly increased average HR in pentobarbital (approximately 28 beats/min.) [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51], and urethane anesthesia (approximately 32 beats/min) [52][53][54][55][56][57][58][59][60]. In female rats under pentobarbital anesthesia, baseline HR values were reported in only one study, depending on the LD Table 1.…”
