The role of hormonal changes during pregnancy in Brugada syndrome is unknown. Only rare case reports of Brugada syndrome during pregnancy have been published. In this article, we describe a patient with first clinical manifestation of Brugada syndrome during pregnancy. The definitive diagnosis could only be achieved by drug challenge with ajmaline after childbirth because the spontaneous typical Brugada-like pattern was absent. Elevated hormone levels during pregnancy may increase the risk for arrhythmias in particular cases.
