Abstract：
Cardiac electrical stimulation in children usually is needed in the setting of complete congenital atrioventricular block, atrioventricular block after heart surgery, and bradycardia associated with some specific channelopathies. In cases of atrioventricular block, the high percentage of ventricular stimulation raises 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 risen in offering conduction system pacing also to the pediatric population. We present three 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 new techniques.
摘要：
在完全先天性房室传导阻滞的情况下，通常需要对儿童进行心脏电刺激，心脏手术后房室传导阻滞，和心动过缓与一些特定的信道病有关。在房室传导阻滞的情况下，高比例的心室刺激引起了人们对右心室慢性刺激的有害影响的关注.近年来,生理刺激已发展成为成人患者的有效方法,并且对向儿科人群提供传导系统起搏也引起了极大的兴趣.我们介绍了3例小儿传导系统刺激（希氏束或左束支），以显示这些新技术所隐含的内在特殊性和挑战。
