Effects of Chronic Right Ventricular Pacing in Children With Advanced Atrioventricular Block

Brazil140 participantsStarted 2007-11

Plain-language summary

Recent studies have shown that chronic stimulation of the right ventricle can cause deleterious effects to cardiac function and synchronicity. The occurrence and consequences of this phenomenon in children and young patients with cardiac pacemaker due to advanced atrioventricular block (AVB) are still unknown. Thus, our aims is to assess the chronic effects of cardiac pacing in children and young patients with advanced AVB and its impact on clinical, functional and echocardiographic parameters.
