A: atrial contraction C: tricuspid closure, start of systole X: ventricles emptying due to ventricular contraction V: venous filling with atrial relaxation Y: ventricular relaxation and tricuspid opening, allowing blood to flow from the atrium to the ventricle
A correction.The atria is not completely emptied in the Y descent. (if it did, then there would be nothing to push out during the following "a" wave). Instead, the pressure pushes about 70% (passively) into the ventricle once the tricuspid opens. The remaining 30% is pushed out during the follow "a" wave contraction. Simple video. Keep it up.
well explained but c is due to the tricuspid bulging into the RA which is due to right ventricle contraction . When right ventricle contract it will push tricuspid valve towards atrium not towards ventricle.
True for c wave (i.e. there is tricuspid bulging due to isovolumetric contraction leading to a JVP wave) which she did not mention. She mentioned that c wave was due to tricuspid closure, but not ventricular contraction. But her triscupid bulge towards ventricle is mentioned during x descent. Which is correct, i.e. that after isovolumetric contraction causing a bulging tricuspid toward the atria (resulting in a c wave), in rapid ventricular emptying, the tricuspid is pulled down, causing the x' descent and a lowered JVP.
closure of the tricuspid gets the jerk on to the closed tricuspid valve giving rise to ' C' thus coinciding with tricuspid closure and impact of contraction of the Rt venricle on to the tricuspid valve.
this is incorrect.. C is for RV contracting against closed tricuspid and X' is due to atrial relaxation and downwarddisplacement of closed tricuspid valve during ventricular contraction.
Ok correct me if I am wrong x' is when atrial continue to relax and allow for more filling V is when atrial have reached max filling Y is when ventricles start to relax and allow some blood flow into ventricle therefore a decrease in pressure Therefore the venous filling actually help to fill both right atrial and right ventricle
isnt the X' is continuation of X (atrial relaxation).. which is interrupted by C(tricuspid bulge).. i mean ti say is X and X' are the same thing...C just coming in the middle..
On explanation of your wave,did you say: atrial completely emptying? Because Atrium or in that matter any chamber of heart never completely get emptied.
hey, hows it going? Thanks or the video! Really useful while im cramming for the steps! Anyway, are you in medical school? Would love to get in touch with you for some collaborative ideas for more medical videos!
what the fuck, totally wrong explaination how rt ventricular contraction can cause the x' decent it's due to atrial relaxation after the tricuspid closure.

A: atrial contraction
C: tricuspid closure, start of systole
X: ventricles emptying due to ventricular contraction
V: venous filling with atrial relaxation
Y: ventricular relaxation and tricuspid opening, allowing blood to flow from the atrium to the ventricle

tq so much for your help and support for the explanation................
love this video! thanks so much. but clarification--- "c" is for ventricular contraction : ) the tricuspid valve cannot contract
Indeed it is incredible way to memorize such an important clinical approach , thank you do much hope you all the best .

Beautifully explained . Kindly mention tricuspid 'contraction' as closure so the that even less confusion amongst students ! Thanks.
fantastic video. I was really struggling to remember but now easy peasy. Any more videos??????
Really appreciate the comment .....I am working on some.....keep getting caught up with work.....
You have a gift for explaining everything so simply! Fantastic teacher, thank you :) 4th year UCL medical student.

Beautifully explained like narrating a movie 👍 completely with it till the last

I agree.. the c is incorrectly explained.. It's the tricuspid bulging into the RA when it's closed and RV contraction that causes c

this is incorrect.. C is for RV contracting against closed tricuspid and X' is due to atrial relaxation and downwarddisplacement of closed tricuspid valve during ventricular contraction.
That's awesome..
thank you :) you have a very special way to deliver info. keep it up !!
Assalaamoalaikom.... jazakAllah (thanks) for mad it easy to us ......nabeel ahmad from ayub medical college abtabad ....
tricuspid closes, you have a typing error in your notes.(you wrote tricuspid contracts). good work
Thank you so much! I am so grateful for people like you who make the time to make the video and upload for us medical students to learn from!
Thank you, that was extremely helpful!
Ok correct me if I am wrong
x' is when atrial continue to relax and allow for more filling
V is when atrial have reached max filling
Y is when ventricles start to relax and allow some blood flow into ventricle therefore a decrease in pressure
Therefore the venous filling actually help to fill both right atrial and right ventricle
I love your voice and the way u speak.can hear it all day ☺️
excellent ...cheers to you ...lovely video
Thankyou
thanx nice and easy
Thanks, always hated JVP waves but you made it so easy to remember 👍👍👍

she's a legend and played a huge role in me passing step 1 and step 2... does anyone know why she stopped making videos???
Just got busy with life. I made these videos for myself as I would learn a new concept. Thinking of getting back as I am more settled now.
Thanks alot for a great vid,
So there is Atrial emptying before Atrial contraction?? I don't understand Dat part
So much easy 💝❤️💝❤️
Awesome simple explanation!

Amazing! Great job, thank you so much!!
This is great 👍
Well explained, but quite a few errors unfortunately, and these can possibly lead to misconceptions, which are much difficult to correct later on.
Shams.
nice video easy to remember
thanks .
Thanks a ton! This really helped!
On explanation of your wave,did you say: atrial completely emptying? Because Atrium or in that matter any chamber of heart never completely get emptied.
Method to your madness 😂😂.. thanks for the video
thank you so much. helped me a lot.
Nice ... good presentation
Awesome, thank you!
thanks alot for help.. you're great!
Great tutorial!
This was awesome!
Really useful,Keep it up!
this is great! thanks x
wonderful!!!

you should do this more often
excellent
nice video,,,
Correction, it’s tricuspid closure , not contraction . Nice video
Nice video, finally the graphical image is in my coconut head. lol
Amazing ! Thank youuu
❤️❤️❤️ i like your explanation
awesome job 😻😻
keep it up
nyc1...
nice one..thanx
Mnemonics good but lil bit wrong..
C wave due to back pressure of av valve during ventricular systole..
Thank you so much!
Thank you Lady
awesome !!
thanks a lot
Thank you so much ♥️
Thank you so much
YOUR AMAZING! thnx!! =)
thank you
Good qork dear
Thank you :)
Needs improvement. Good attempt but with some silly explanation and mistakes.
Which software you are using??
RV Contra(xi)on sounds nice
❤️
Theres a few errors in the info, better redo the video
cute.... lols
ax cx' vy yaay thanku *-*
This is totally wrong. please dont mislead people
