You are incorrect - the best description of the acoustic events at the upper left sternal edge in our patient is a short, mid systolic murmur and a second sound that is split in inspiration and single in expiration.
Your choice: Short, mid systolic, S2 split in inspiration, split in expiration
This is a graphic example of a short, mid systolic murmur, with a widely split second sound in inspiration. It does not change in expiration, that is, the second sound demonstrates fixed splitting.
