Lecture 2 Flashcards
1
Q
A wave
A
From the increased pressure from the atrial kick(10cc).
2
Q
C wave
A
From the backward bowing of the valve during isovolumetric contraction(phase 2)
3
Q
V wave
A
From volume accumulating in the atria during systole. Towards the end of ejection, right before the AV valves open up.
4
Q
1st heart sound
A
AV valve closing
5
Q
2nd heart sound
A
Aortic valve closes. shorter duration cause more meaty.
6
Q
3rd heart sound
A
should not hear in healthy adult. happens towards the end of rapid filling.
7
Q
RAP(right atrial pressure)
A
0mmHg
8
Q
LAP(left atrial pressure)
A
2mmHg
