Abstract:Objective To discuss the effect of senate pine spiritual cultivation capsule on heart rate variety(HRV) and QT dispersion(QTd) of patients with coronary heart disease(CHD). MethodsRandomly divide 192 CHD patients into observation group(98 cases) treated with senate pine spiritual cultivation capsule and control group(94 cases), and then observe the changes of indexes related to HRV, QTd and corrected QTd(QTcd) between the two groups respectively before and after the treatment. ResultsAfter the treatment, indexes related to HRV all increased while QTd and QTcd both decreased with a comparatively significant decrease in the observation group. The differences between the two groups were statistically significant(P<0.01). ConclusionIt indicated that senate pine spiritual cultivation capsule could effectively raise indexes related to HRV and reduce QTd, and thus improve the balance of autonomic nerve and prognosis and prevent ventricular arrhythmia.
