MedCram - Medical Lectures Explained CLEARLY
Sure i will someday iA.
Thank you. Goodness gracious I had a hard time finding a good explanation.
I read Hurst and Braunwald about this topic and didn't understand. Then I search for this video, and I clearly understand this now.
Thanks MEDCRAM. Great video.
Thanks for the feedback Dr. Putra. Glad we could help clarify
Thank you! Great general conceptual review. Nice to link or include practical aspect of measuring CVP for those asked to measure it.
How to remember acxvy
a = Atrial contraction
c = triCuspid valve closure
x = atrial relaXation
v = passiVe filling into atria
y = atrial emptYing/tricuspid valve opens
V wave is " volume " wave.I remember it like that
I really appreciate your re-iterating summary at the end. I'm not a med-school student or clinician at all (BME), but this really made helped me make sense of this. Thank you!
10:58 Villing:) greetings from a german student studying Med in Poland
haha
Nice video! I finally understood it. Thanks from Taiwan!
keep these videos coming! They are really helping me through medschool
These video are concise, reliable and helpful. I would like to suggest and request for ECG series.
Thank you for explaining it perfect! Greets from Spain!
A=Atrial contractionC= Closure of triCuspidX = relaX (atria)V= Venous returnY = emptYing atria (passive phase)
I was actually watching this to figure out if C was truly tricuspid closure or carotid pulse--I watched a 1957 venous wave form video that said there isn't a "C" wave in atrial pressure tracings, but only when using a pneumatic jugular pressure tracing--but a cardiologist explained this as Closure of tricuspid, but gave no further evidence--is it ACTUALLY seen on a central line? That would solve the problem all together.
Great video! Thank you for sharing knowledge!
Very clear explanation, thanks!
Excellent! Very comprehensive presentation. Thanks
Amazing video. Thank you so much
Excellent explanation
So awesome! Best explanation video!
Thanks sir it helps a lot ,made it simpler for me to revise the whole concept ,kudos!!
singham jadeja glad the video helped- thanks for the comment
This always confused me until I learned that what the eye percieves on exam is not what you see in a pressure trace. In normalcy, all you can visualize is the X descent falling onto the second heart sound.
Any thing related 2 cardio is amazing
Excellent explanation! 👍🏻
Thank you for this videos ! I wish you could make one for hypernatremia!
Nice & simple
Your videos are so useful, I'm using them to revise a lot for my UK med school exams, so thank you!
Do you have any resources for looking into the changes in inspiration and expiration in more depth? What do you mean when you say that you have different waveforms throughout the respiratory cycle?
So clear. Awesome.
mashallah! wonderfull explaination
You are the man
Thanks a lot for the super clear, well organised and great explanation
Clearly explained..thank you
+Mahesh Gaikwad Thanks for the feedback
excellent work
Thank you so much! Great video
+Jessie L Thank you for the feedback
Thank you so much! Very helpful :)
explained clearly indeed! god bless!
bgchgc hvkhc Thank you for the comment
Thank you so much!!
amazing video thanks
The only thing i do not understand about this curve is the v wave and y descent curves... I mean after the x descent, if the atrium is filling up to cause the (v wave) while tricuspid is closed... after its filled up totally, it starts to contract to push the blood to the ventricle... this should cause another (&should be named) A wave (not that what is so called V wave)... cause how would the blood flow to the ventricle without an atrial systole!!!!? Thats my point....
Can u understand what I mean !??
Can anybody explain this to me!?
As I recall, atrium contracts at ventricular telediastole, and before that both atrium and ventricle are relaxed and filling passively (isotonic phase). Tricuspid opens when both atrium is partially filled and ventricle relaxed enough to be distensible again. This curve represents intraatrial pressure throughout cardiac cycle, one should think that intraventricular fluxes are somewhat different and how they influence the overall atrial flow and pressure. It would be useful to add a sinchronous ECG and a ventricular pressure curve for a better orientation.
Dr.Albert
Which one happen first,Atrial Contraction or open of valves?
Answer is valve open first then contraction happen to forcefully clear the blood to ventricle.
You can start for C wave instead of A wave for better understanding.
Hope this helps
The atrial does not need to contract at V. This is the beginning of the diastolic phase, hence the blood flows passively from RA into RV (upon opening of the tricuspid) as the RV is relaxed and "pulling or sucking" the blood. This is similar to the diastology concept in the LV :-)
Hi, Y wave is actually not Rt atrial emptying, its Rt ventricular diastole, due to Rt ventricular diastole, tricuspid valve will sag a bit and that will couse y descend , which will lead a bit more filling of Rt Atrium , soon after that atria will will contract and form a A wave. There is a bit mistake in this video i think. If Y decend is Rt Atrial emptying into Rt ventricle then what follows after A wave which is actually Rt Atrial contraction.?
Eyeshath Hucen Blood normally flows continually from the great veins into the atria even after V phase, but as the AV valve opens then after due to initiation of ventricular diastole, about 80 percent of the blood flows directly through the atria into the ventricles even before the atria contract (represented by v-y descent). Then, atrial contraction (a wave) usually causes an additional 20 percent filling of the ventricles (a-x descent).
Wonderful thanks a lot
thanks
thank you alot
I don't understand how v wave pattern is formed if v wave is venous filling of the right atrium against a close valve. Closing of a valve precedes a contraction, then why the tricuspid valve would be open? if no contraction present then why is there an opening of the tricuspid valve?
Thank you! I guess part 2 is not on TH-cam...
Go to www.medcram.com
Can you please tell me what program you use for this explanation?
thanks alot :)
you the man tank you so much
Where is the link to part 2 of 2? I don't see it under the "About" tab
is the 2nd part there???
its not jugular venous pulse veins never pulsates they throw oscillations or waves we can actually differentiate veins from arteries on the basis of pulsations its jugular venous pressure(jvp) btw good demo
Does JVP stand for Jugular Venous Pulse or Jugular Venous Pressure? This seems to be referring to two different things.
+Anthony Emmott They are often used for each other.
Can anyone send the link of part 2?
Hey please explain deep x wave pleasee
Hello Sir.
Why is 2nd video not available ?
i dont get it. What is happening during atrial contraction? doesnt the blood move into the ventricle because the atria is contracting? please explain the difference between the "a" wave and "y" wave.
+Qtip783 I know you're probably beyond this now, but in case anyone else watching the video is confused (as was I):
the y wave is "passive" (the pressure in the atria builds up enough from filling to overcome the pressure of the ventricle and this opens the tricuspid; because the pressure difference is so great, the atria doesn't actually have to contract yet in order to push blood through to the ventricle)
the a wave is "active" (because the pressures are no longer so different between atria and ventricle due to blood volume, to get the rest of the blood out, the atria have to ACTIVELY contract to push the rest of the blood through and keep the tricuspid valve open; this contraction maintains a high enough pressure so that the tricuspid doesn't close)
Is the 2nd part gone?
in confused! the tricuspid valve opens before atrial contraction? if V is tricuspid valve opening and a (atrial contraction) comes afterward, it seems like the atria contract after AV valves open, and not at the same time. is that correct? plz help!
+Yaniv Hadi tricuspid valve opens as soon as pressure in the right ventricle falls below that of the right atrium. As blood fills the ventricle and the pressure equalizes the valve almost closes again only to be opened wide with the atrial contraction and then closed rapidly with ventricular contraction. Then the cycle repeats itself.
MEDCRAMvideos i have a query...... when a wave produced by right atrial contraction then blood pushes to the right ventricle throgh the tricuspid valve, isn't it?
So before you write "Tc" there shouldn't be a "To"?
I need your answer.Thank you.
+MEDCRAMvideos plz
+Sheikh Mohammad Ullah - Yes - To correlates with the "a" wave. Tc correlates with the beginning of systole.
nyc
×=isovolumetric ventricular contraction !!
I think its just the first part of X because X ends right when the T wave on an EKG starts (ventr. repol)
