AuscultifyHow to Learn Heart Murmurs: A 4-Step Method That Sticks
Most students try to learn heart murmurs by memorizing a list — aortic stenosis is a crescendo-decrescendo systolic murmur, mitral regurgitation is holosystolic, and so on. Then they put a stethoscope on a real chest and hear none of it. The problem isn't the list; it's that a murmur is a sound, and you can't learn a sound by reading about it. Here's the method that actually works.
Step 1: Anchor every murmur to the cardiac cycle first
Before you name anything, place the murmur in time. Feel the carotid pulse (or watch the timing marker in a training app): a murmur that coincides with the upstroke is systolic; one that fills the gap after it is diastolic. This single distinction eliminates half the differential instantly, because the common systolic and diastolic murmurs barely overlap.
Step 2: Locate the point of maximal intensity
Where the murmur is loudest points to its origin:
| Location | Loudest murmur to suspect |
|---|---|
| Right 2nd intercostal space (aortic area) | Aortic stenosis |
| Left 2nd intercostal space (pulmonic area) | Pulmonic stenosis, flow murmur |
| Lower left sternal border | Tricuspid regurgitation, VSD |
| Apex | Mitral regurgitation, mitral stenosis |
Step 3: Describe the shape, pitch and radiation
Now characterize it. Is the intensity crescendo-decrescendo (diamond-shaped, like aortic stenosis) or uniform/holosystolic (like mitral regurgitation)? Is it high-pitched and blowing, or low and rumbling? Does it radiate — to the carotids in aortic stenosis, to the axilla in mitral regurgitation? These qualities are what separate murmurs that share the same timing.
Step 4: Train with repetition and immediate feedback
This is the step textbooks can't give you. Research on murmur teaching is consistent: repetitive listening with immediate answer feedback is what moves students from guessing to recognition. One published curriculum moved students from a mean pretest score of under 4/9 to over 7/9 using repeated, described audio modules. The mechanism is active recall — retrieving the answer yourself, then being corrected — not re-reading descriptions.
Practice this method in Auscultify
Auscultify's Heart Sounds mode plays a real patient recording and asks "what do you hear?" You commit to an answer, then see the correct finding with its clinical reasoning — the exact retrieve-then-correct loop above. Missed murmurs are re-queued until you master them, so your weak spots get the most reps. All on 245 recordings captured across the four classic auscultation areas.

- Days 1–2: Learn normal S1/S2 cold so abnormal sounds stand out.
- Days 3–4: Add the systolic murmurs (aortic stenosis, mitral regurgitation).
- Days 5–6: Add diastolic murmurs and extra sounds (S3, S4).
- Day 7: Mixed quiz — no category hints. This is the real test.
Ten minutes a day beats one long cram session, because auditory memory consolidates with spacing. Keep a streak going through your cardiology block and the sounds become automatic.
