Does LV apex/LV midlateral wall pacing prevent pacing-induced reduction of cardiac pump function in children who require lifelong pacing?
In children requiring lifelong pacing, targeting the LV apex or midlateral wall for ventricular pacing may best preserve cardiac pump function and mechanical synchrony.
The site of ventricular pacing has a major impact on LV mechanical synchrony, efficiency, and pump function in children who require lifelong pacing. Of the sites studied, LV apex/LV midlateral wall pacing has the greatest potential to prevent pacing-induced reduction of cardiac pump function.
Janoušek et al. (Mon,) studied this question.
