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