ABSTRACT
Objective To explore the feasibility of right ventricular outflow tract (RVOT) septal pacing. Methods Fifty-two patients implanted with pacemaker were randomly divided into two groups. One group underwent the RVOT septal pacing with active fixation electrodes (active fixation electrodes group, 22 cases),and the other group underwent the right ventricular apical pacing with passive fixation electrodes (passive fixation electrodes group, 30 cases). The parameters of two groups in operation were recorded. Results The successful rate of RVOT septal pacing was 100%, active fixation electrodes group took more time to plant electrodes and expose in X-ray than passive fixation electrodes group [ (56.13±1.18)min vs (15.42±1.24) min, (18.77±6.14) min vs (10.12±8.14) min, P<0.05]. The width of the QRS wave of active fixation electrodes group was narrower than that of passive fixation electrodes group [(0.14±0.02)ms vs (0.16±0.04) ms, P< 0.05]. The parameters of two groups were stable in follow-up period and none of electrodes was extracted. Conclusion The usage of active fixation electrodes in patients with RVOT septal pacing is feasible and safe.
