CVP Flashcards
1
Q
what causes a wave?
What does it correspond to on ECG?
A
increased R atrial pressure during R atrial contraction.
Corresponds to p wave
2
Q
What causes c wave? Where does it correlate on ECG?
A
Elevation of tricuspid during v contraction.
correlates to end of QRS
3
Q
what is x descent. Where does it correlate on ECG?
A
downward movemet of QRS during systolic contraction. before t wave
4
Q
What is v wave? where does it correlate on ECG?
A
Blood filing R atrium impacts closed tricuspid. Occurs as t wave is ending
5
Q
What is y wave?
A
opening of tricuspid valve. occurs before t wave.
