Mnemonic

Murmur Description

A mnemonic for describing a heart murmur completely.

SCRIPT: Site, Character, Radiation, Intensity, Pitch, Timing

Expansion

SCRIPT:

  • S - Site of maximal intensity
  • C - Character: ejection, pansystolic, early diastolic, mid-diastolic
  • R - Radiation: aortic stenosis to the carotids, mitral regurgitation to the axilla
  • I - Intensity, graded 1 to 6
  • P - Pitch: high pitched murmurs are best heard with the diaphragm, low pitched with the bell
  • T - Timing: systolic or diastolic, established by palpating the carotid simultaneously

Levine grading

  1. Very faint, heard only with concentration
  2. Faint but immediately audible
  3. Moderate, no thrill
  4. Loud with a palpable thrill
  5. Very loud, thrill, audible with the stethoscope partly off the chest
  6. Audible with the stethoscope off the chest

Manoeuvres

  • Inspiration accentuates right-sided murmurs; expiration accentuates left-sided (RILE)
  • Sit forward in expiration for aortic regurgitation
  • Left lateral position for mitral stenosis
  • Valsalva and standing reduce most murmurs but increase those of hypertrophic obstructive cardiomyopathy and mitral valve prolapse
