Selective left bundle branch pacing for pediatric complete heart block.

Shunmuga Sundaram Ponnusamy, Giridhar Muthu, Dasarath Bopanna,

Traditionally Right Ventricle has been the preferred site of pacing for the management of symptomatic brady-arrhythmias. The deleterious effect of chronic RV pacing has been shown by several studies. This has generated interest into a novel pacing strategy called physiological pacing wherein the His bundle or the left bundle is ... Read more >>

Anatomy of the septal perforating arteries of the heart.

Sung Deuk Kim,

The septal perforating arteries of the heart usually branch off from the anterior and inferior interventricular arteries and supply the interventricular septum and the conduction system therein. Since the septal perforating arteries are not directly visible from the outside of the heart, their anatomy and variations might be overlooked. However, ... Read more >>
