BRASH syndrome is a syndrome characterized by bradycardia, renal failure, usage of atrioventricular (AV) nodal blocker, shock, and hyperkalemia (BRASH). It is more common among patients with multiple comorbidities such as cardiac disease, kidney dysfunction, and hypertension requiring AV nodal blockers. Cardiac conduction abnormalities are frequently caused by severe hyperkalemia. However, it may also occur in mild-to-moderate hyperkalemia with concomitant use of AV nodal blockers due to the synergistic effects between these two factors in the presence of renal insufficiency. It is essential for the physician to identify BRASH syndrome as the treatment may differ from standard advanced cardiovascular life support (ACLS) protocol. We report the two cases of patient who presented with BRASH syndrome who failed to respond to standard ACLS protocol.
