Multiple lithium‐dependent Brugada syndrome unmasking events in a bipolar patient

Abstract

This case demonstrates two important points about Brugada syndrome unmasking: electrocardiograph abnormality severity may correspond to lithium levels and unmasking may occur in the therapeutic range of lithium. Also, the correlation of CACNA1C with Brugada and Bipolar suggests allelic disequilibrium, leading to a subpopulation of bipolar patients sensitive to arrhythmia.
