Key result
Acute MI with pronounced right precordial ST depression can mask type 1 Brugada ECG patterns.
Why the study?
Overlap between ST-segment changes in Brugada syndrome and ischemia can cause diagnostic challenges.
Case Report (n=1)
No
Acute ischemia-induced ST depression can mask the characteristic ST elevation of Brugada syndrome on ECG, potentially complicating diagnosis.
May obscure Brugada diagnosis during acute ischemia; single case leaves open systematic ECG surveillance needs.
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.

Törngren et al. (2024) conducted a case report in Brugada syndrome and acute myocardial infarction (n=1). Acute myocardial infarction with pronounced ST depression in the right precordial leads can mask the baseline type 1 ECG pattern in a patient with Brugada syndrome.
