A Case of Bradycardia, Renal Failure, Atrioventricular Nodal Blockade, Shock, and Hyperkalaemia (BRASH) Syndrome in an Elderly Male and Its Management: A Case Report and Literature Review.

BRASH syndrome, characterized by bradycardia, renal dysfunction, atrioventricular (AV) nodal blockage, shock, and hyperkalemia, is a rare but potentially life-threatening condition resulting from the interplay between AV nodal blockers and hyperkalemia. This complex syndrome poses significant challenges in diagnosis and management, with patients often presenting with bradycardia and high potassium levels. This case report highlights the need for increased awareness of BRASH syndrome, especially in an aging population and evolving cardiovascular treatments. Early recognition and a comprehensive, multidisciplinary approach are crucial for improving outcomes in affected patients.
