Case presentation of acute ischemia induced ST-depression masking Brugada syndrome ECG pattern in a relatively young patient.

ECG in Brugada syndrome (BrS) is characterized by a ST-segment elevation in the right precordial leads. Overlap between ST-segment changes in BrS and ischemia may lead to diagnostic challenges. We report a case of a male patient presented with recurrent chest pain episodes and ST elevation in the right precordial leads consistent with Brugada ECG pattern type 1 and was clinically diagnosed with BrS at the age of 30 years. During follow up the patient developed acute myocardial infarction with pronounced ST depression in the right precordial leads, masking the Brugada pattern of the baseline ECG.
