Q

Normal splitting

A
S1 A2|P2
during inhalation (drop in intrathoracic pressure, increased venous return, longer pulmonary ejection time)
2
Q

Wide splitting

A

S1 A2| |P2
Conditions that delay RV emptying (pulmonic stenosis, RBBB)
Exaggeration of normal

3
Q

Fixed splitting

A

S1 A2| |P2

Seen in ASD (increased RV filling). Always there, similar to wide splitting…

4
Q

Paradoxical splitting

A

S1 P2| |A2
Delayed LV emptying (aortic stenosis, LBBB)
P2 occurs before A2 which is abnormal.
On inhalation, P2 is prolonged, moves closer to A2, can be no splitting

5
Q

(Maneuver and effect)

  • Inhalation
  • Exhalation
  • Hand grip
  • Valsalva
  • Rapid squatting
A
  • Increased right heart sounds
  • Increased left heart sounds
  • (increased SVR) Increased intensity of MR, AR, VSD, MVP murmurs (all things where flow is going backwards); decreases intensity of AS, HCOM (less fluid moving forwards to make a big sound)
  • (decreased venous return/preload increases LV outflow obstruction) increases intensity of MVP and HCOM
  • (increases venous return/preload) decreases HCOM
