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: Long, mid systolic murmur, S2 single in inspiration, single in expiration
This is a graphic example of a long, mid systolic murmur, with a second sound that is single in both inspiration and expiration. Note that the systolic murmur is high frequency and that it peaks in late systole.
