| Abstract: | Objective To assess the heart rate deceleration capacity(DC), aceleration capacity(AC) and their association with heart rate variability(HRV) in 80 health adults, and investigate DC as a way for determination of cardiac autonomic nervous function. Methods Using 24h Holte recordings, DC, AC, time and frequency domain parameters of HRV were obtained from 80 health adults in the daytime (15:00~20:00) and at night (00:00~05:00) respectively. Results It was found that the values of DC were increased at night tha... |
