The Cardiac Function Research in Patients with Right Ventricular Septum Pacing / 昆明医科大学学报

ABSTRACT

Objective To compare the cardiac function effect of right ventricular septum(RVS) pacing with that of right ventricular apex(RVA) pacing.Methods One hundred and six patients with indication of dual chamber pacemaker implantation were divide into two groups randomly.In each patient,influence of different pacing site to LVEF and pacing parameter were examined and left ventricular eject fractions were compared.Results All patients' operation were successful,LVEF of RVS group compared with that of RVA showed a significant difference.Conclusion The cardiac function are significantly different between right ventricular septum pacing group and right ventricular apex group.
