Abstract：Objective To investigate the effect of psychological support on heart rate turbulence(HRT) in patients with coronary heart disease accompanied with depression. MethodsOne hundred and ten outpatients and inpatients with coronary heart disease in the Department of Cardiology of our hospital were enrolled and their depression status were assessed by Zung’s self-rating depression scale(SDS). Fifty patients with coronary heart disease complicated with depression were chosen as the subject investigated.Fifty cases were randomly divided into observation group(25 cases)and control group(25 cases).Besides conventional drugs, the observation group accepted psychological support treatments.All enrolled patients were performed 24-hour ambulatory electrocardiography.Their HRT parameters including HRT onset(TO) and HRT slope(TS) and SDS scores were measured, respectively one week after being chosen and two weeks after being treated.ResultsCompared with the control group, the depression status of the observation group was improved and HRT was enhanced further.ConclusionHRT of patients with coronary heart disease complicated with depression shows significant decrease.Combining drug therapy with psychological support can elevate patients’ HRT, improve the function of vagus nerve and the prognosis.
