BRASH syndrome is composed on five findings: bradycardia (slow heart rate), renal failure, AV node dysfunction, shock (low blood pressure), and high potassium.[1]

Treatment should be directed towards low blood volume, slow heart rate, and high potassium.[1] Low volume can be treated with ringer's lactate if bicarbonate is high or isotonic bicarbonate if bicarbonate is low.[1] Low heart rate should be treated with 3 amps of calcium gluconate and isoproterenol or epinephrine.[1]


Isoproterenol has the benefit over epinephrine in that it increases heart rate without decreasing blood flow to the periphery.[1]
