That's the complete exam-oriented review of Chapter 194 from Tintinalli's. Here's what's covered:
Structure designed for exam success:
  • Section 1 - Mechanism/pharmacology (MCQ favorite: cAMP pathway, Ca²⁺ signaling)
  • Section 2 - Drug property table (propranolol vs sotalol vs atenolol are the most-tested)
  • Section 3 - Clinical features system-by-system with exceptions (sotalol, pindolol)
  • Section 4 - DDx table for bradycardia + hypotension with distinguishing features
  • Section 5 - Full treatment algorithm with exact doses (the core of every board question)
  • Section 6 - Disposition criteria (the 6-hour rule is a classic question)
Top 3 exam traps from this chapter:
  1. Sotalol is not like other B-blockers - it's a class III agent causing TdP, not just bradycardia
  2. Glucagon bypasses the blocked receptor (acts on adenylate cyclase directly) - that's why it works
  3. HDI = inotrope, not just glucose support - insulin drives glucose into the stressed myocardium as energy substrate, which is mechanistically different from all other agents
