Thanks. I am a medical student. I especially appreciated your getting realistic about those "classic signs" (head bob, etc) of aortic regurge that we learn about in medical school. So now I know, that what I learn for the exam, and what I'll believe for clinical practice, won't be the same. Wish there was more honesty like this in medical school.
Dr. Eric, thanks for your clear explanation. In this lecture clip, you have mentioned that sometimes it could be hard to distinguish AR with PR. Is there any other clues in physical examination that could possible allow us to better differentiate both? thanks!
The pulse pressure (systolic BP minus diastolic BP) in AR is usually very large, where it should be normal in PR. In severe, acute AR (from aortic dissection or endocarditis), there is almost always evidence of left sided heart failure (i.e. crackles), while crackles may or may not be present in PR, depending on the cause of PR. (Interstitial lung disease leading to pulmonary hypertension leading to PR could also have crackles for example, though typically a different quality crackle than heart failure). Finally, in chronic AR, the PMI will usually be displaced from LVH, whereas it should be normal in isolated PR.

Thank you Dr Strong. It is nice to have your commentary regard to those signs. I just heard this the first time. ,
This was most excellent.
very interesting, the best part and useful for me was when you indicate the specificity and sensitivity of each eponym sign.

Great video Eric!
+Errol Ozdalga Thanks! It's one of my first, so production quality isn't great. Was still figuring out sound and the software.
thank you very much :) the explanation was clear ^^
Thanks for the response
Thank you!
Thanks for valuable information. But why heart beat skips still not properly known
thank you very much
Genius !
Dr I kindly asked you to do other valvular diseases too 💓
