3 Atrial Septal Defect
    Cardiac Exam - Auscultation ULSE

You are incorrect - our patient's systolic murmur at the upper left sternal edge is best described as short, early peaking and crescendo-decrescendo.

Your choice: Long, late-peaking + crescendo-decrescendo

This is a graphic example of a systolic, long, late-peaking, crescendo-decrescendo murmur.

Note that the murmur is mid-frequency.
