ACLS Revision: Hyperkalaemia

Learning Points:

1. When a patient is bradycardic, especially if irregular, one must always think of hyperK and one must get a 12-lead ECG.
2. One must recognize this pattern as hyperK
3. Calcium’s effect is almost miraculous
4. Slow atrial fibrillation implies an sick AV node, or one affected by electrolytes, ischemia, or medications/drugs.  Otherwise, the ventricular response should be fast.
