We examined 24 hour heart rate variability (HRV) components and baroreflex sensitivity (BRS) in elderly adults. Forty-eight subjects, aged 65-69 years old (24 men, 24 women) were examined in this study. BRS was measured in the morning (8:00-9:00) using noninvasive cross spectral analysis. There were significant correlations between BRS and low-frequency (LF) power (r = 0.593, p < 0.001) of HRV, and between BRS and high-frequency (HF) power (r = 0.402, p < 0.005). BRS values were lower in women compared with men (p < 0.01), and LF/HF was significantly lower in women than in men (p < 0.05).
