Permanent Conduction System Pacing Versus Atrioventricular Management for Patients With Wide QRS and Patent AV Conduction

Intraventricular conduction delay alone or in combination with AV conduction delay is associated with a dyssynchronous activation of the ventricles and may result in LV function impairment. Conduction system pacing can restore physiologic ventricular activation in the presence of intraventricular and atrioventricular conduction delays. Patients with intraventricular conduction delay alone or in combination with AV conduction delay who have a permanent pacemaker indication due to intermittent bradycardia and have predominantly intact AV conduction may benefit from continuous CSP.
