Resumo: Circadian variation of Spilotes pullatus (Colubridae). The circadian rhythm of  the mean heart rate and RR and QT intervals in electrocardiograms were determined for Spilotes pullatus in normal cycle (day/light and night/dark) conditions, during springtime. The statistical analysis of the results revealed significant differences among time intervals, using Tukey’s test. Heart rate and body temperatures demonstrated considerable variations in their respe- ctive values over the 24h monitoring period and long circadian rhythmicity in the electrocardiogram intervals (p<0.05). In addition, significant reductions of  the heart rate and an increase in RR and QT intervals were also observed. Multiple influences on QT interval dependence were found, not only in circadian and gender modulation, but also in heart rate.

Análise estatística dos resultados revelou diferenças significativas entre  intervalos de tempo, usando o teste de Tukey. A freqüência cardíaca e  a temperatura corporal demonstraram uma grande variação nos seus respec tivos valores no período de 24h de monitoramento,e longo ritmo circadiano foi demonstrado nos intervalos dos eletrocardiogramas (p<0,05). Além disto, também é observada uma significativa redução da freqüência cardíaca e um aumento dos intervalos RR e QT. O intervalo QT sofre múl- tiplas influências, podendo constituir não apenas modulações circadianas e de gênero, mas também a freqüência cardíaca.Universidade Federal de Santa Catarina2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21097Biotemas; v. 19 n. 4 (2006); 49-532175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/21097/19067Copyright (c) 2006 José Geraldo Pereira da Cruz, Ayrton Adão Schmitt Júnior, Marcelo Reinerthttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessPereira da Cruz, José GeraldoSchmitt Júnior, Ayrton AdãoReinert, Marcelo2022-11-21T11:48:28Zoai:periodicos.ufsc.br:article/21097Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2022-11-21T11:48:28Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false
