Jugular venous pulses Flashcards
1
Q
a wave
A
atrial contraction
2
Q
c wave
A
right ventricular contraction
3
Q
x descent
A
atrial relaXation
4
Q
v wave
A
increases in right atrial pressure from filling
5
Q
y descent
A
right atria emptYing into right ventricle
6
Q
When is a wave absent?
A
a. fib
7
Q
When is x descent absent?
A
tricuspid regurg (right atria never gets to relax because of all the reflux)
8
Q
When is x descent prominent?
A
- tricuspid insufficiency
- right HF
9
Q
When is y descent absent?
A
cardiac tamponade (atria does not empty into ventricle in tamponade because ventricle constricted)
10
Q
When is y descent prominent?
A
constrictive pericarditis (because magic)
