Abstract:
Objective To compare the impacts of right ventricular outflow tract pacing and right ventricular apical pacing on short-term cardiac function, QRS duration and pacing parameters in children undergoing VVI pacemaker therapy. Methods The clinical data of 38 children undergoing VVI pacemaker treatment in our department from July 2006 to November 2013 were retrospectively reviewed and analyzed to make grouping: 22 with right ventricular outflow tract pacing based on the operational records were assigned in one group and 16 with right ventricular apical pacing as the other group. The two groups were compared in terms of cardiac function indexes , QRS complex width and intra- and post- operative parameters of the implanted pacemakers. Results There were no significant differences between the two groups in pre-and post-operative cardiac function indexes , intra- and post-operative difference in pacing thresholds, pacing wire impedance and R-wave amplitude. The pre-and post-operative QRS duration [(134.95 ± 12.86)ms vs.(147.44 ± 22.35)ms, t=1.35, P=0.01] was statistically significant between the groups. Conclusion The right ventricular outflow tract pacing for children patients is safe and feasible. Although the two pacing approaches achieved lengthened duration of QRS, the right ventricular outflow tract pacing is more effective in lengthening the duration of QRS.
