This case report describes the clinical course of a 77-year-old woman with a complex medical history, including atrial fibrillation, hypertension, coronary artery disease, heart failure, and cognitive impairment. Despite multiple hospitalizations and interventions, her condition deteriorated, ultimately leading to death. The patient's most recent hospitalization was for the management of bradycardia, renal failure, atrioventricular node blocker, shock, and hyperkalemia (BRASH) syndrome. Aggressive medical interventions, including pressor support and non-invasive ventilation, were unable to stabilize her condition. This case highlights the challenges associated with managing elderly patients with multiple comorbidities, particularly when faced with severe bradycardia and hypotension.
