Abstract
Objective To investigate the influence of circadian rhythm disorders of blood pressure on heart rate in elderly hypertensive patients.Methods 200 elderly patients with isolated systolic hypertension were selected and divided into three groups [dipper type (n =56),non-dipper type (n =80)and reverse-dipper type (n =64)] according to the ambulatory blood pressure,32 healthy individuals were recruited as control group.All the patients and healthy subjects were submitted to 24-h ambulatory blood pressure monitoring.The 24 h daytime and nighttime heart rate and heart rate variability were recorded.Results The heart rate of hypertensive patients with non-dippers and re-verse-dipper was significantly higher than that of patients with dipper and healthy subjects (P <0.01,P <0.05);The values of SDANN、SDNN、rMSSD、PNN50D were significantly lower in the reverse-dippers type group(P <0.01, P <0.05)compared with those of dippertype and non-dipper type group,the heart rate was positively correlated to the average systolic and diastolic blood pressure during the daytime and nighttime (P <0.05).Conclusion The circadi-an rhythm disorders of blood pressure is associated with higher heart rate and lower heart rate variability.关键词
