ABSTRACT

Objective:

To explore the correlation betWeen deceleration capacity of heart rate (DC)and heart rate var-iability (HRV)in patients With essential hypertension (EH)complicated coronary heart disease (CHD).

Methods:

DC and HRV Were monitored in 81 patients With EH + CHD (EH + CHD group)and 80 healthy volunteers (healthy control group)respectively.

Results:

Compared With healthy control group,there Were significant decrease in DC [(11.99±4.93)ms vs.(6.62±1.83)ms],standard deviation of normal to normal RR intervals calculated o-ver the 24 h period [SDNN,(129.94±15.22)ms vs.(63.66±12.13)ms],root-mean square of differences be-tWeen successive normal to normal intervals [rMSSD,(55.52±9.03)ms vs.(28.25±8.81)ms]and adjacent nor-mal RR interval difference > 50ms stroke accounted for a percentage of 24h total RR interval [PNN50,(13.99± 5.63)% vs.(7.29±1.11)%]of HRV in EH + CHD group,P <0.05 all;Pearson correlation analysis indicated that DC Was positively correlatedWith SDNN,rMSSD and PNN50 in EH+CHD patients (r =0.571,0.662,0.763, P <0.05 all).

Conclusion:

There is positive correlation betWeen deceleration capacity of heart rate and heart rate variability in patients With hypertension complicated coronary heart disease,Which can be jointly used as evidence for diagnosis and treatment.
