Administration of increasing doses of the tricyclic antidepressant desipramine induced prominent Brugada waves in a patient, suggesting a potential mechanism for sudden death risk with these drugs.
Case Report (n=1)
Since its initial description in the early 1990s, the Brugada syndrome has become increasingly familiar to active researchers and practicing clinicians. The Brugada wave, a characteristic electrocardiographic abnormality of downsloping ST-segment elevation in leads V1-V3 and right bundle-branch block morphology, has now been associated with an increased risk of sudden death. Currently, very little is known about the relationship between the Brugada syndrome and tricyclic antidepressants. Accordingly, we report the case of a patient who developed prominent Brugada waves with the administration of increasing doses of desipramine. We believe the mechanism of Brugada wave augmentation or production secondary to tricyclic antidepressants is consistent with the current model of early repolarization. We also speculate that the increased risk of sudden death that may occur with tricyclic antidepressants could be related to the development of the Brugada syndrome. We advocate the judicious use of tricyclic antidepressants in cardiac and elderly patients, with careful monitoring of the electrocardiogram for the development Brugada waves.
Babliaros et al. (Thu,) conducted a case report in Brugada syndrome (n=1). Desipramine (tricyclic antidepressant) was evaluated on Development of Brugada waves. Administration of increasing doses of the tricyclic antidepressant desipramine induced prominent Brugada waves in a patient, suggesting a potential mechanism for sudden death risk with these drugs.
