A split second heart sound is:
a. abnormal.
b. greatest at the peak of inspiration.
c. heard best after forceful expiration.
d. supposed to disappear with deep inspira-tion.
B
Splitting of S2 is an expected event because pressures are higher and depolarization occurs earlier on the left side of the heart. Ejection times on the right are longer, and the pulmonic valve closes a bit later than the aortic valve. Splitting of S2 is greatest at the peak of inspiration. During expi-ration, the split may disappear.
