Key result
In a patient with right bundle branch block, manual optimization of atrioventricular delays achieved significant QRS narrowing, whereas the automated Sync-AV algorithm failed to do so.
Why the study?
Does manual optimization of AV delay improve QRS narrowing compared to nominal Sync-AV settings in a patient with RBBB receiving a BIV-ICD?

Does manual optimization of AV delay improve QRS narrowing compared to nominal Sync-AV settings in a patient with RBBB receiving a BIV-ICD?
In patients with RBBB receiving CRT, nominal Sync-AV settings may fail to achieve electrical synchrony, and manual optimization of AV delays may be required to narrow the QRS complex.

Rashid et al. (2022) conducted a case report in Ischemic cardiomyopathy with right bundle branch block (n=1). Manual optimization of atrioventricular delay vs. Sync-AV algorithm on (nominal settings) was evaluated on QRS narrowing. In a patient with right bundle branch block, manual optimization of atrioventricular delays achieved significant QRS narrowing, whereas the automated Sync-AV algorithm failed to do so.
