Fascicular premature ventricular contractions (
PVC
s) can arise from anywhere in the His Purkinje system, but
PVC
s originating from the left bundle branch (
LBB
) are rarely reported. We report the case of
PVC
arising from the
LBB
, and also describe the electrophysiological features that might indicate the bracketing of the fascicular
PVC
focus.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
