When interpreting a CVP waveform, the end of systole best coincides with the
ExplanationC. In the CVP waveform depicted below, 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 Ydescent occurs when the tricuspid valve opens and the atrium starts to empty.
