Can't see the dip between A and C in the graph!
Thanks for the note, now the dip can be seenCan't see the dip between A and C in the graph!
That would be of great help, anyone please do so if you come across any question like that.can u post high yield questions regarding this JVP curve plz........
. 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.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.
