WebUnlike systolic sounds, diastolic sounds are low-pitched; they are softer in intensity and longer in duration. Except for S2, these sounds are usually abnormal in adults, although an S3 may be physiologic up to age 40 and during pregnancy. S2 occurs at the beginning of diastole, due to aortic and pulmonic valve closure.
