The Cardiac Cycle and PV Loops 

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.

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

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.

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

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

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.

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

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

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

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?

The best, others got me confused

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.

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

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)

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?

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

thanks for this amazing video !

Are there another videos in this series?!

PERFECT!
