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
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
