Summary: | The analysis of heart rate variability (HRV) in the time domain was performed by dynamic electrocardiographic monitoring for twenty-four hours (Holter method) in ten male and ten female healthy mixed-breed dogs before and after four weeks of oral supplementation with long-chain polyunsaturated fatty acids (PUFAs) derived from omega n-3 [497 mg docosahexaenoic acid (DHA) and 780 mg eicosapentaenoic acid (EPA)]. Males received an average dose of 34.9 mg DHA/kg and 22.2 mg EPA/kg, whereas females received an average of 27 mg DHA/kg and 43 mg EPA/kg. HRV indices calculated in the time domain were the following: NN, SDNN, SDANN, SDNN index, pNN50, rMSSD and heart rate, taking into account the effects of gender and supplementation. The results showed no significant effects of supplementation or gender on the indices; thus, dietary supplementation with omega PUFAs derived from n-3 over four weeks did not decrease heart rate and did not increase heart rate variability in healthy dogs. |

Os índices da VFC calculados no domínio do tempo foram: NN, SDNN, SDANN, SDNN índex, pnn50 e rMSSD e frequência cardíaca, verificando-se o efeito do sexo e da suplementação. Os resultados obtidos não demonstraram efeitos significativos da suplementação ou influência do sexo sobre os índices; a suplementação dietética com PUFAS derivados do ômega n-3 por quatro semanas não diminuiu a frequência cardíaca e não promoveu elevação da VFC em cães saudáveis.Pró-Reitoria de Pesquisa (PROPE UNESP)Universidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Medicina Veterinária e Zootecnia (FMVZ), Departamento de Clínica Veterinária, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Medicina (FMB), Departamento de Clínica Médica, Botucatu, SP, BrasilUniversidade Federal do Pampa (UNIPAMPA), Faculdade de Medicina Veterinária, Uruguaiana, RS, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Instituto de Biociências (IBB), Departamento de Bioestatística, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Medicina Veterinária e Zootecnia (FMVZ), Departamento de Clínica Veterinária, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Faculdade de Medicina (FMB), Departamento de Clínica Médica, Botucatu, SP, BrasilUniversidade Estadual Paulista Júlio de Mesquita Filho (UNESP), Instituto de Biociências (IBB), Departamento de Bioestatística, Botucatu, SP, BrasilUniversidade Estadual Paulista (Unesp)Universidade Federal do Pampa (UNIPAMPA)Santos, Thiago Hideky Yamauti dos [UNESP]Araújo, Maíra Mont'Alvão Guedes de [UNESP]Gonçalves, Renato de Souza [UNESP]Sudano, Mateus JoséMachado, Luiz Henrique de Araújo [UNESP]Carvalho, Lídia Raquel de [UNESP]Lourenço, Maria Lucia Gomes [UNESP]2016-07-07T12:34:24Z2016-07-07T12:34:24Z2014info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article2453-2462application/pdfhttp://dx.doi.org/10.5433/1679-0359.2014v35n4suplp2453Semina.
