A study on the circadian rhythms of patients with congestive heart failure
The circadian rhythm of heart rate variability(HRV) was assessed in 29normal subjects(group Ⅰ )
27 patients with cardiovascular diseases
whose cardiac function was fully compensated (group Ⅱ)
and 27 patients with congestive heart failure (group Ⅲ) by using time domain analysis. The 24-h plot of HRV showed that the physiological ciacadian rhythm was preserved in group Ⅱ
In contrast
there wasless diurnal variation in HRV for group Ⅲ. Our results suggest that the circadian rhythm of HRV is correlated with the seventy of cardiac insufficiency.
