CVP pneumonic

Different waves of CVP

A wave- atrial contraction
C wave- chordae contraction aka isovolumic ventricular contraction
V wave- Vena caval blood against closed tricuspid valve in late systole after t wave
X descent- xx atrial relaxation xx
Y descent- right Yentricular relaxation

Remember XY is bigger in size than XX so X wave due to smaller RA relaxation and Y wave due to larger RV relaxation and X wave comes before Y wave since ladies first

No A wave- Atrial fibrillation- can be lethal on aortic stenosis
Cannon A wave- junctional rhythm due to atria contracting against closed tricuspid valve
tall Significant A wave- tricuspid Stenosis also silent Y descent in tricuspid stenosis

IV drug abuse- leading to tricuspid regurgitation - cv wave merge and  eliminates X descent so IV drug abuse eliminates the chances to get  a lady XX
