The Cardiac Cycle and PV Loops

[@TheNotedAnatomist]

Exceptional video tutorial! Your key points were so clearly delivered and i loved how simplified your graphics are. Thank-you!

[@tiago4007]

You deserve a million subscribers. I hope you never stop making videos - yours is the best medical channel on KZbin. Thank you so much for your wonderful work. Much love from Brazil.

A brilliant video..As always..Nice visual representation of common clinical scenarios and physiology/pathophysiology behind them. Thank you for bringing these brilliant and highly informative videos. Love from India.

I have a test in 6 hours on these concepts! Wicked timing! Thank you, Dr. Strong!!

[@The_syncretist]

Thank you very much Dr Strong, an excellent learning resource I have followed your channel for 7 years, I remember refining my understanding of PFT interpretation from your videos years ago. I have since completed training in Respiratory Medicine. I continue to enjoy watching your excellent videos, they are particularly useful for my ongoing critical care training.

Thank you so much! I'm very glad the videos have been helpful!

One of the best videos on pv loop. Thank you very much

[@sunving]

Thank you very much Doctor Strong. I just get through first round as always I thank you that “ if you can not remember anything , please remember the picture of loop” I love this :) . You are a great lecturer despite this I will have to watch this many time to somewhat get it. Time fly this is about to end the year already.

Thank you so much. Pv loop has been difficult to understand from looking at the paper alone. This video helped me so much!

Superb explanation of difficult concepts and correlation with clinic. Thank you.

[@texastexas4541]

Please answer this question. I think all textbooks show it wrong. SV increases as EDV increases and they all shorten to the same ES point on the ESPVR curve. Why should it shorten to the same end systolic pressure or point? If you increase SL (as in higher EDV) you should get more force (Force-length relationship) and more force means higher pressure. If they all shortened to the same ESP when you increase EDV, how would they even get the ESPVR curve?

You are a GREAT teacher. You know exactly what to say for clarity and effectiveness. At 8:26 for point 2, is it DB or MAP? My teacher told me it is MAP. Thanks.

thanks for this amazing video !

Great lecture in 22 minutes. Thanks Dr. Eric. Are you considering topics like HCM or ARVC in future videos ?

[@StrongMed]

Thanks for the comment! I may someday incorporate HCM and ARVC/ARVD into this specific series, but I'd have many more videos to get through before reaching them (heart failure, CAD, arrhythmias, etc...). In the meantime, I do have a video that covers HCM and ARVC from an EKG diagnosis perspective (but covers a little of the genetics/pathophys as well): kzbin.info/www/bejne/gp6UeXSjeNOlb6M

[@aliasgharabbasi1155]

PERFECT!

[@youssefkhial6791]

thank you Dr Eric .. I have one question, ginving the fact that coronary artery disease is the number one cause of heart failure, how do you explain the fact that heart failure patients rarely develop angina (independently of its mechanism)

[@texastexas4541]

6 min Time independent? Why? Doesn't contraction (isovolume cont) and relaxation (Isovol rel) depend on time as well?

[@lola-mo5sh]

The best, others got me confused

[@The_syncretist]

Thank you as always Dr Strong, I've followed your channel since 2016. Would you consider future videos on selected haematological malignancies and the foundations of their chemotherapeutics?

[@7amzawi-Senpai]

Are there another videos in this series?!

[@StrongMed]

As of now, this series on cardiovascular physiology has 5 videos, but is ongoing and will probably end up with 10-11 (depending on whether I decide to include cardiac embryology). I'm hoping to post the next one on hemodynamics in ~2 weeks. kzbin.info/aero/PLYojB5NEEakWY3ZS0acDMw4nbEZV-y7pk
