Abstract:Objective To evaluate the relationship between morning blood pressure surge and heart rate variability(HRV)in the patients with hypertension. Methods Fifty-six patients with hypertension were performed by 24-hour ambulatory blood pressure monitoring. They were divided into with morning blood pressure surge group(31cases)and without morning blood pressure surge group(25 cases)according to the condition of 24-hour ambulatory blood pressure monitoring. The deviation of the average value in awaking 2 hours and the minimum value during sleep of the systolic blood pressure no less than 55 mmHg was defined as morning blood pressure surge. Their HRV time domain indexes were analyzed. Results The SDNN,SDANN,SDNN,PNN50 of morning blood pressure surge group were significantly higher than without morning blood pressure surge group. Conclusion The autonomic nerve function was damaged and electrophysiological instability of ventricular myocardium increased significantly in hypertension patients with morning blood pressure surge.
