Heart rate variability indices in the time domain in healthy dogs supplemented with omega n-3

A analise da variabilidade da frequencia cardiaca (VFC) no dominio do tempo, foi realizada por meio da monitorizacao eletrocardiografica dinâmica em vinte e quatro horas (Holter), em caes sadios, sem raca definida, sendo dez machos e dez femeas, antes e apos suplementacao oral, por quatro semanas com acido graxos poliinsaturados de cadeia longa (PUFAS) derivados do omega n-3 [497 mg acido docosahexaenoico (DHA) e 780 mg acido eicosapentanoico (EPA)], resultando em uma dose media de 34,9 mg/kg de EPA e 22,2 mg/kg de DHA em machos e media de 43 mg/kg de EPA e 27 mg/kg em femeas. Os indices da VFC calculados no dominio do tempo foram: NN, SDNN, SDANN, SDNN index, pnn50 e rMSSD e frequencia cardiaca, verificando-se o efeito do sexo e da suplementacao. Os resultados obtidos nao demonstraram efeitos significativos da suplementacao ou influencia do sexo sobre os indices; a suplementacao dietetica com PUFAS derivados do omega n-3 por quatro semanas nao diminuiu a frequencia cardiaca e nao promoveu elevacao da VFC em caes saudaveis.
