Isolated hyperkalemia
BRASH syndrome (Bradycardia, Renal failure, AV node blockade, Shock and Hyperkalemia)
2. Reduced vital signs
Hypoxia
Hypoglycemia
Hypothermia +/- hypothyroid
3. Acute coronary occlusion
Inferior MI: nodal ischemia and vagal response, self-limiting or responds to atropine
Anterior MI: infranodal ischemia, often requires pacing
4. Drugs: withdraw if stable, reverse if unstable
Beta-blockers
Calcium channel blockers
Digoxin
5. Intracranial pressure, Infection (Lyme, endocarditis): treat underlying
