Abstract:
Objective To investigate the advantage and disadvantage of the right ventricular outflow septal pacing.Methods Eighty patients requiring pacemaker because of slow arrhythmia were randomly divided into the active fixation group and passive fixation group.The implantation time, radiation exposure time and changes of electrocardiogram were compared between 2 groups,and the heart function changes 1 year after treatment were observed by color Doppler ultrasound.Results The implantation time and radiation exposure time in active fixation group were significantly longer than those in passive fixation group: (20.00 ± 3.48) min vs.(15.00 ± 2.67) min and (9.45 ± 3.48) min vs.(6.78 ± 2.67)min,and there were statistical differences(P<0.05).The QRS duration and QTc duration in active fixation group were significantly shorter than those in passive fixation group:(0.119 2 ± 0.042 1)s vs.(0.142 3 ± 0.032 4)s and(0.403 5 ± 0.026 8)s vs.(0.442 7 ± 0.054 1)s,and there were statistical differences(P<0.05).In active fixation group,there were no statistical differences in left atrial diameter, left ventricular end-diastolic diameter, left ventricular minor axis decurtaion rate and left ventricular ejection fraction, compared before treatment and 1 year after treatment (P>0.05).Conclusions The application of the active electrode lead in the right outflow trace septal pacing is more associated with wider physiological ventricular function.
