Abstract
Acute pancreatitis (AP) refers to the acute inflammation of the pancreas; however, if there is concurrent necrosis, it is called necrotizing acute pancreatitis (NAP). The diagnosis is sometimes difficult because it might mimic acute coronary syndrome (ACS). We report a case of a 28-year-old male, who presented to the emergency department (ED) with severe epigastric pain, shortness of breath and diaphoresis for 4-5 h. The initial electrocardiogram (ECG) showed marked sinus bradycardia with an incomplete left bundle branch block. Considering the clinical presentation and ECG changes, he was managed as ACS and was rushed to catheterization laboratory for a coronary angiogram, which was reported normal. Subsequently, his serum pancreatic enzymes were elevated, and computed tomography of the abdomen showed NAP. In ED settings, it is difficult to differentiate between the two, particularly when AP presents with ECG manifestations masquerading as ACS.
