Here is a quick mnemonic “EARLY DIASTOLIC MURmur to remember about Early Diastolic Murmurs

This can be valuable for patients as well as medical doctors, nurses & students doing their clinical rounds. You can also find it very useful for med exams like USMLE, NExT Medical Step 1&2, MBBS, NEET PG, INI-CET, FMGE,MCAT & NCLEX exams

Early Diastolic Murmurs : How To Remember Easily ?

  • EEarly onset: The murmur begins after the aortic component of S2.
  • A Aortic root disease: The murmur may radiate along the right sternal border.
  • RRadiation clue: The location of radiation provides a clue to the cause.
  • LLeaning forward: To hear the murmur better, auscultation is performed with the patient leaning forward.
  • YYoung patients: Valve diseases like congenital bicuspid disease can cause the murmur.
  • DDiastolic turbulence: The murmur occurs during diastole, indicating regurgitant and forward blood flow.
  • I – Interspaces: Best heard at the second right interspace and along the left sternal border.
  • A – Austin Flint murmur: In severe AR, a lower-pitched mid-to-late diastolic murmur may be heard at the apex.
  • S – Soft and difficult to hear: The murmur may be soft and challenging to detect.
  • T – Turbulence at mitral inflow: The Austin Flint murmur reflects turbulence at the mitral inflow area.
  • O- Opening snap: Absence of an opening snap helps differentiate from mitral stenosis.
  • L – Lowering afterload: A vasodilator challenge can decrease the duration and magnitude of the murmur.
  • I – Increased cardiac output: The murmur of mitral stenosis may increase with afterload reduction.
  • C – Coexistent AS: Coexisting aortic stenosis may make identification difficult.
  • M – Midsystolic murmur: Coexistent AS can cause a crescendo-decrescendo midsystolic murmur at the base.
  • U – Unprepared left ventricle: Acute, severe AR shows a rapid rate of rise of diastolic pressure.
  • R – Rapid heart rate: The diastolic murmur may be difficult to appreciate with a fast heart rate.
