Title: Ajmaline-induced Brugada Phenocopy, Right Bundle Branch Block, or Both? Cord-id: vuzqha32 Document date: 2021_9_15
ID: vuzqha32
Snippet: In equivocal or suspected cases of Brugada syndrome (BrS), ajmaline testing is frequently used in the diagnostic approach. However, the administration of sodium channel blockers can not only elicit the coved ST-segment elevation characteristic of type 1 Brugada pattern but also induce right bundle branch block (RBBB), which can preclude the electrocardiographic manifestations of BrS. We describe a case report wherein RBBB posed a diagnostic challenge during the ajmaline test for suspected BrS.
