Unmasking of infra‐Hisian conduction abnormality by intravenous isoproterenol during electrophysiology study for syncope

Year: 2021

Type: article

Abstract: Recurrent unexplained syncope in the background of bundle branch block (BBB) often requires a pacemaker. But the decision-making for pacemaker is difficult in case of single episode of syncope with intermittent bundle branch block. We encountered one such case with intermittent LBBB, where the results of invasive EP study were even normal, until intravenous isoproterenol unmasked the infra-Hisian disease during decremental atrial pacing.
