You are incorrect - our patient's acoustic events at the lower left sternal edge demonstrate a third heart sound (S3) and a fourth heart sound (S4) heard during inspiration. Normal first and second sounds are also heard.


Your choice: S3 and diastolic murmur

This is a graphic example of a first and second heart sound with a third heart sound and a diastolic murmur. Note that the third sound and the murmur are low frequency.
