Case Presentation: A 68-year-old female presented with non-ST-segment elevation myocardial infarction, and urgency coronary angiography was performed. The procedure was complicated with right coronary artery dissection leading to type-1 Brugada ECG pattern.
Discussion: Brugada phenocopies (BrP) are clinical entities that present with electrocardiograms identical to those found in Brugada Syndrome (BrS) but are the result of different medical conditions. This report provides evidence that atypical causes of myocardial ischemia may induce BrP. Appropriate electrocardiogram and clinical differentiation of Brugada phenocopy from true Brugada syndrome may prevent unnecessary treatments. Although patients with true high-risk BrS are candidates for ICD therapy, the natural history of BrP remains unknown and seems to be more benign, depending on the severity of the underlying condition.

Sudden death after myocardial infarction (MI) is associated with electrophysiological heterogeneities and ionic current remodelling. Low ejection fraction (EF) is used in risk stratification, but its mechanistic links with pro-arrhythmic heterogeneities are unknown. We aim to provide mechanistic explanations of clinical phenotypes in acute and chronic MI, from ionic current remodelling to ECG and EF, using human electromechanical modelling and simulation to augment experimental and clinical investigations.

Background: Brugada phenocopy (BrP) is a condition that induces reversible Brugada-like electrocardiographic (ECG) changes in patients without true Brugada syndrome. We present two cases of fulminant eosinophilic myocarditis that showed Type 1 Brugada ECG changes in the early phase of the clinical course.
Case Summary: Case 1 was a 76-year-old man who developed fulminant eosinophilic myocarditis with ventricular tachycardia while hospitalized for heart failure.

Management of patients with drug-induced type 1 Brugada pattern is complex and controversial. We report the case of a 66-year-old man affected by metastatic lung adenocarcinoma with type 1 Brugada phenocopy at electrocardiogram (ECG) after initiation of an oncological therapy with BRAF and MEK inhibitors.

Article Synopsis
- - Brugada phenocopy (BrP) is characterized by a Brugada-like ECG pattern and can occur due to various conditions, but it doesn't increase the risk of serious heart issues like Brugada syndrome (BrS) does.
- - A case is presented of a 69-year-old woman with moderate hyponatremia who exhibited a saddle-back ST-segment elevation on her ECG, which was linked to her liver metastases compressing her heart.
- - The ECG changes resolved quickly after treating her hyponatremia with sodium chloride, demonstrating that even mild electrolyte imbalances can lead to BrP when compounded by other factors like mechanical heart compression.
