“…The supplementation for four weeks was capable of reducing the serum levels of cholesterol and triglycerides (ARAUJO et al, 2012); however, it was not enough to influence the autonomic tone or induce changes in the intrinsic activity of the cells of the cardiac pacemaker 24 (BILLMAN; HARRIS, 2011).…”

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

“…The rMSSD and pNN50 indices reflect the HRV across short periods and are predominantly influenced by the parasympathetic tone; in contrast, SDNN, SDANN and SDNN indices are influenced by the sympathetic and parasympathetic tone and reflect long-term HRV (BIGGER et al, 1989, 1992DERKENNE;VON BERNUTH, 1999).…”
