Approximately 50% of left bundle branch blocks are associated with structural heart disease, while the other half are idiopathic or due to fibrosis of the cardiac conduction system which occurs ...

The normal conduction system in the ventricles is called the His-Purkinje system and consists ... A widened QRS duration occurs in the setting of a right bundle branch block, left bundle branch ...

particularly the His–Purkinje network and bundle branches, in arrhythmogenesis remains unclear. The extent of cell loss, remodeling, and repair in the ventricular conduction system after MI is ...

Abbott's investigational AVEIR™ Conduction System Pacing (CSP) leadless pacemaker system is specifically designed to deliver pacing to the left bundle branch area, activating the heart's natural ...

These procedures mark the first time a leadless pacemaker has been implanted into the left bundle branch area, a key part of the heart's electrical conduction system, designed to mimic the heart's ...

Much has changed since the 2013 document came out, with new information on pacing devices, techniques, and more.
