A premature ventricular contraction occurs when a focus in the ventricle generates an action potential before the next scheduled sinoatrial nodal action potential. Premature, occurring earlier than ...

Duplication or absence of parts of the specialized cardiac conduction system in patients with heterotaxy syndrome causes significant clinical disease, but the mechanistic basis by which embryonic ...

INJURY to the invisible subendocardial conduction system during surgical closure of congenital defects in the ventricular septum is an uncommon but extremely grave complication. 1,2 Impalement of ...

Physiologic pacing of the His-Purkinje conduction system is feasible in patients who require a permanent pacemaker following TAVR and this alternative pacing method did not interfere with ejection ...

Patients with atrioventricular (AV) block who don’t have an indication for cardiac resynchronization therapy (CRT) do better when treated with conduction-system pacing versus right ventricular septal ...
