Objective\ To in vestigate the change of the premature ventricular complexes(PVC)and the heart rate variability(HRV)before and after the treatment of Sotalol on PVC patients.Methods\ To observe the different index of HRV in 50 cases with PVC by means of 24h.ambulator ECG before and after the use of Sotalol,the other 50 cases with PVC as the control.Results\ After the therapy of Sotalol,the SDNN,SDANNI and SDNNI that showd the total HRV significantly(P

Relationship between ambulatory pulse pressure and left ventricular hyp ertrophy and enlarged diameter of aorti c root in aged patients with essential hypertension / 中国实用内科杂志

Objective To find out the relationship between ambulatory pulse pressure (24 h PP) and left ventricular hypertrophy (LVH) and the enlarged diameter of aortic root (AOD) in aged pati ents with essential hypertension.Methods 118 aged patients with essential hypertension we r e examined by ambulatory blood pressure (ABP) and echocardiography,the different index of ABP and left ventricular mass index (LVMI) and AOD were measured.The p atients were divided into group A (24 h PP≥60 mmHg) and group B (24 h PP
