What is the prognostic implication of right bundle branch block in asymptomatic coronary artery disease patients?
Metadata[+] Show full item record
In patients with asymptomatic coronary artery disease (CAD), complete right bundle branch block (RBBB) likely increases mortality risk compared with similar patients without complete RBBB. (SOR: B, based on 3 cohort studies with heterogeneous results.) Incomplete RBBB in patients with CAD does not affect mortality risk. (SOR: B, based on 1 cohort study.)
