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, early systolic, S2 split in inspiration, single in expiration
This is a graphic example of an early systolic murmur, with a second sound that is split in inspiration and single in expiration. Note that the murmur begins simultaneously with the first heart sound.
