In most cases, the percentage of ventricular stimulation is high, so there is concern on the deleterious effects of chronic stimulation of the right ventricle. In recent years, physiologic stimulation has developed as a valid approach for adult patients and a great interest has arisen in offering conduction system pacing also to the pediatric population. We present 3 pediatric cases of stimulation of the conduction system (His bundle or left bundle branch), in order to show the intrinsic particularities and challenges implied in these techniques.
