These notes cover everything in the chapter, restructured for exam recall. Key things to anchor:
  • CCB class determines HR response: non-DHPs (verapamil/diltiazem) = bradycardia; DHPs ("pines") = reflex tachycardia
  • Hyperglycemia is a toxicity marker (blocked pancreatic beta-cell insulin)
  • Treatment ladder: Atropine (often fails) → Calcium → HDI (1 unit/kg bolus, up to 10 units/kg/hr) → Vasopressors (MAP goal ≥65) → Glucagon → Lipid emulsion → ECMO
  • HDI protocol numbers are frequently tested: bolus 1 unit/kg, infusion 1-10 units/kg/hr, glucose check every 15-20 min
  • SR formulations = mandatory 24-hour admission regardless of initial appearance
