The Node of Randy is what stimulates the Conceptocyte, causing the Know to Flow. Viva El Randy!

This has become part of my routine now.

👏👏 ! I’ve seen my share of videos on the cardiac action potential and this one is by far ,the best ! It is the most practical , high yield and designed to be easily understood . The mnemonic with the banana, the salt shaker , and the bone 🦴 is great, those symbols stick in your head and well , suddenly all that complexity melts. God bless you Dr for the work you do. You are making all us better doctors .

Cardiology is my favorite subject, the last question, I studied in UW too.but you explained the topic very well and it was very informative and helpful.

Amazing work. Thank you soo much Dr. Randy. This is the BEST Cardiac Myocyte & pacemaker physiology/action action potential video. You made it crystal clear and easy to memorize. Also love the last question with the Equilibrium potentials (E): K=-81mV Na =61mV and Ca=128mV, making it easy understanding that K does efflux from cell, while Na and Ca influx into cell to Equilibrium. One of the BEST USMLE Channels.

Your methods of simplifying seemingly complex concepts are really commendable, Dr. Neil! Thank you so much!!

thanks A LOT Dr Neil,

You are the greatest teacher and the most knowledgeable expert I have ever seen! The only source of motivation of me to study is your great videos thank you so much 💐💐🌺🌺👏👏

It's strange how we don't know how much we needed that concept or story unless you make it into an informative video for us, and do so many questions with that single concept. It helps us redirect our ways of learning and takes so much load off the memory. How you solved the last 2 questions was commendable, they have been very confusing for me until now.

Dr randy thank you from the bottom of my heart .. the world needs more people like you

God bless neil. thank you

Words aren't enough to say how amazing you are! Thank you so much!!

I am always happy to watch a video by you, Dr. Neil. I know once I start a video that here’s something complex that will become simplified and that I will never forget again. You are a lifesaver. Thank you for your time to create the videos.

very helpful thank you Dr Randy

thank u so much doc! always had the problem with electric potential questions..keep doing the good job! :)

You made this so clear! Thank you sooo much, you're awesome! :)

Very useful, thank! More videos of cardio will be appreciated

Blasting through your videos, amazing stuff. Any videos on pre post and Intrarenal azotemia in the pipeline ? Fantastic work

Very helpful!!! Thank you so much

Thank you so much! You are amazing!!!watching your videos like a netflix series marathon🙂

Nicely Explained thank you so much sir.

Excellent.please put more videos around cardio

Excellent presentation

Thank you Randy, you are great, please more video about cardio..

THANKS DR ♥️ 😊 WE NEED ANOTHER VIDEOS OF CARDIO PLEASE 🥺

Please do cover the whole cardiology unit 🤢 A poor girls silly wish Exam is in one month and still not that great in cardiology

very helpful , thank u

I wish you could do one on sympathomemtc drugs when added together? Like Epi with phenylephrine and how that affects the cardiogram. This topic is still the hardest for me and no resource explained it good

Great video again randy .. Could you pls post a video on virology basics (recombination reassortment shift drift transformation) part

Thanks sir!

another great video, thanks again.sir if you could make some videos on respiratory pathophysiology ,would be really helpful.

Hey Dr. Neil, very helpful video. Any chance you could make a video on Public Health Sciences (i.e Medicare, latent error) I was never really taught it that would be amazing if you could make a video about it

Thank you very much sir again you nailed it nd simplified beautifully kindly make video on cardiac & vascular function curves nd pressure volume loops. Thanks in advance Sir🙏

pacemaker-- NaCaK 034 -60mv cardiomyocyte- KNakcak 01234 -90mv

Please continue CVS series..... Btw love from India☺☺☺

very nice

How do I find Randy’s summary notes???

I have a question confused me the reason why resting potential in pacemaker cell is about -60 mv while the other contractile cell is -90 mv ?? That means the membrane is already leaking to Na+ before we talk about "funny channel"???
