That's the complete murmur guide, structured from first principles to advanced clinical application. Here's a quick orientation to what's covered:
Sections at a glance:
  1. What causes murmurs - the 3 turbulence mechanisms
  2. Cardiac cycle - the timing framework everything hangs on
  3. Levine grading scale - 1-6 with the thrill threshold
  4. 8 attributes to describe any murmur
  5. Master diagram from Harrison's 22E showing all murmur waveform patterns
  6. Systolic murmurs - AS, PS, HCM, innocent murmurs, MR, TR, VSD, MVP
  7. Diastolic murmurs - AR (with all peripheral signs), PR, MS, TS
  8. Continuous murmurs - PDA machinery murmur
  9. Dynamic maneuvers table - the HCM/MVP rule is the highest-yield exam topic here
  10. Master summary table - all murmurs in one place
  11. Diagnostic flowchart from Harrison's
  12. Innocent vs. pathologic checklist
The two things most students get wrong early on:
  • Confusing timing (HCM murmur is systolic, not diastolic despite being due to obstruction)
  • The MVP/HCM maneuver rule: decreased LV volume = louder murmur for both; just remember Valsalva and standing do that, while squatting reverses it
