ABSTRACT
Objective To observe the effect of bisoprulol on malignant ventricular arrhythmia (MVA) and heart rate turbulence (HRT) in ambulatory electrocardiogram monitoring for twenty-four hours in patients with unsta-ble angina pectoris (UAP). Methods 40 UAP patients with premature ventricu]ar beats were observed. All patients were examined with ambulatory electrocardiogram monitoring for twenty-four hours before and after bisoprolol (5mg, Qd) was administered for 7 days. The number of patients with MVA、turbulence onset (TO) and turbulence slope (TS) were analyzed. Results After bisoprolol was administered for 7 days in patients with UAP,the number of pa-tients with MVA decreased by 14.2%. TO decreased and TS increased, and HRT was improved. Conclusions HRT had clinical prognostic value for malignant ventricular arrhythmia and sudden death in patients with UPA. Bisoprolol can improve HRT and reduce the incidence of MVA.
