The Prognostic Significance of Right Bundle Branch Block: A Meta-analysis of Prospective Cohort Studies.

ABSTRACT:

Background

The prognostic significance of right bundle branch block (RBBB) is inconsistent across studies. We aimed to assess the association between RBBB (in general population and patients with heart disease) and risk of all-cause mortality, cardiac death, acute myocardial infarction (MI), and heart failure (HF).
