Brash syndrome stands for Bradycardia, Renal Failure, AV Node Blocker, Shock and Hyperkalaemia, and is a rare complication of patients suffering from chronic kidney disease, who are usually on dialytic support. These patients are usually on AV node blockers (either calcium channel blockers or beta blockers) and renal failure causes the accumulation of these medicines plus hyperkalaemia.1 Here we present a case of a patient who was diagnosed with Brash syndrome, was treated medically and was discharged. The purpose of this article is to highlight BRASH syndrome, recognise it and improve its’s medical management.
