Transient right bundle branch block causing R wave attenuation postdefibrillation.

PMID:  9121959     Owner:  NLM     Status:  MEDLINE    
Transient and significant decrease in R wave amplitude, associated with transient right bundle branch block, was noted to occur after defibrillation in a defibrillator patient. The mechanism is probably stunning of the right bundle branch, causing right intraventricular conduction delay and decrease in signal amplitude reaching the endocardial sensing dipoles.
