Murmurs and heart sounds

Mitral stenosis

  • Tapping apex beat
  • Loud first heart sound
  • Rumbling mid-diastolic murmur at apex (louder in left lateral position on expiration)
  • Malar flush

Aortic regurgitation
  • Wide pulse pressure
  • Displaced, volume-overloaded apex beat
  • Early diastolic murmur at lower left sternal edge (best heard in expiration leaning forward)
  • Carotid pulsation (Corrigan's sign)
  • Head nodding (De Musset's sign)
  • Capillary pulsations in nail bed (Quincke's sign)
  • Pistol-shot heard over femorals (Traube's sign)

Mitral regurgitation
  • Displaced, volume overloaded apex beat
  • Soft first heart sound
  • Pansystolic murmur at apex radiating to the axilla (louder in expiration)

Tricuspid regurgitation
  • Large systolic 'v' waves
  • Pansystolic murmur lower left sternal edge (best heard in inspiration)
  • Pulsatile hepatomegaly

Aortic stenosis
  • Narrow pulse pressure
  • Heaving undisplaced apex beat
  • Soft second heart sound
  • Ejection systolic murmur heard in aortic area radiating to carotids and apex

Ventricular septal defect
  • Harsh pansystolic murmur  lower left sternal edge
  • Left parasternal heave
