The JVP and the venous pulse / pulsation is a frequently tested concept in USMLE

Here's a quick review

A = Atrial contraction
C = bulging of the tricuspid valve during ventricular contraction
There's dip between A and C which conincides with the Tricuspid valve closure

X descent = is the filling phase when pr decrease then gradually increase as more blood fill the right atrium until it reaches a maximum at

V = which is when the tricuspid opens

Y descent = is the emptying phase where pressure decreases as blood leaves the right atrium and then gradually increase as atria begin to contract going back to wave a.

:) . The "x" descent is due to a combination of atrial relaxation, the downward displacement of the tricuspid valve during right ventricular systole, and the ejection of blood from both the ventricles.
