Intraventricular conduction delay surgery
Introduction
Overview
Overview
Asymptomatic patients with isolated IVCD and no underlying heart disease require no treatment. In symptomatic patients, with syncope and AV block may have a rhythm disturbance that requires a pacemaker. Given the dys-ynchrony that occurs with left ventricular contractility, cardiac resynchronization therapy in heart failure patients may be of benefit.
Surgery
Surgery
Permanent pacemaker may benefit patients with IVCD, if they have concomitant :
- Type 2 second-degree AV block
- Alternating bundle branch block
- Syncope not demonstrated to result from AV block or ventricular tachycardia
- Incidental finding at electrophysiological study of His-ventricular interval ≥100 msec
- Presence of neuromuscular disease
- Fascicular block with or without AV block and symptoms
