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.
在Brugada综合征（BrS）的可疑或不明确病例中，阿义马林试验常用于诊断。然而，给予钠通道阻滞剂不仅可引发1型Brugada波型特征性的穹窿型ST段抬高，还可诱发右束支传导阻滞（RBBB），这可能会掩盖BrS的心电图表现。我们描述了一例病例报告，其中在对疑似BrS进行阿义马林试验时，RBBB对诊断构成了挑战。
