Heartbeat: pacer risk in patients with right bundle branch block
Why the study?
Does the presence of RBBB or LBBB on ECG increase the risk of cardiovascular outcomes such as heart failure or pacemaker implantation?
Population
Over 200,000 individuals in whom 0.4% had an LBBB and 2.6% had an RBBB on ECG

Implication
LBBB is strongly associated with an increased risk of future heart failure, whereas RBBB is more strongly associated with the subsequent need for pacemaker implantation.
