Fentanyl-induced Brugada phenocopy: A case report.

Brugada Syndrome (BrS) is a genetic condition characterized by specific electrocardiographic (ECG) findings and an increased risk of life-threatening arrhythmias. Brugada phenocopy (BrP) refers to reversible ECG changes mimicking BrS caused by external factors, such as drugs or metabolic disturbances. Here, we present a case of a 45-year-old male with Brugada phenocopy due to high-dose of fentanyl transdermal patch.
