When interpreting a CVP waveform, the beginning of systole is best represented by the
- A wave
2) C wave
-
V wave
-
X decent
solution
In the CVP waveform depicted in, the A wave represents atrial contraction, the C wave represents bulging of the tricuspid valve into the atrium during the beginning of systole, the X decent occurs during systole and corresponds to atrial relaxation, the V wave represents filling of the atrium while the tricuspid valve is closed, and the Y descent occurs when the tricuspid valve opens and the atrium starts to empty.
