I can't count the amount of times this channel has saved me in my studies! Please never stop making videos :)

🥺🥺🥺 This man single handedly carrying my entire understanding of Medicine !

I watched this video a few times in undergrad while i was taking an anatomy course & here i am again now that Im in nursing school. no one describes this better than you lol

You don't know how we students love you , you are life saver 💓

Love it! Easy to understand, simple yet complete explanations, thank you!!

I'm a 6th year RN and going back into a cardiac specialty after a couple years away. This made more sense than when I was in Uni. Thanks team!

This is the most helpful thing i’ve watched on youtube so far

You guys are *so wonderful* I don't know how to thank you. Please don't stop helping medical professionals from all over the world! Thank you loads! 💕

Probably the best video out here that helped me understand the whole concept. Thank you so much!

NEVER STOP MAKING VIDEOS DR MIKE! THIS CHANNEL IS LEGENDARY

I’m in paramedic school and your videos have helped way more than any of my lectures or books. Keep up the good work!

im beyond grateful to you Dr. Mike!❤🙏 you're the best!🥺

Thank you SO much for explaining in such an organized way, I am struggling with a professor who is brilliant, but disorganized so I had trouble following all the steps. This is perfect. THANK YOU AGAIN!!!

You my friend have a gift. I could not make sense of this till I saw your video ( which came recommend by my teacher) I love how you give enough info without over loading us and you talk calm and smooth ( not fast and loud) amazing thanks again.

Absolute legend Dr Mike I’d b lost studying 4 my Masters without ur amazing & informative videos. Huge Thank You

This is absolutely the BEST explanation! Until now I honestly thought I was too dumb to grasp the concept of this, but now I realize no one has EVER been able to explained it in a way (to someone who has zero knowledge) that one can get their head around it and truly understand. Not just try remember a whole lot of info and hope it sticks, but completely understand! Which will only aid in further study, of the ECG for example. This then makes the next subject easier to understand and get your head around and so on and so on. Thank you so much!!!! you guys do an amazing job!!!!

I'm so grateful for you I could cry.

Thank you. You really break down all the steps. It really helps me understanding the materials ❤️❤️❤️

Thank you sir No body in my medical school did it like you You're the best ❤❤

I desperately needed this. THANK YOU!

you don't understand how much your videos help me, thank you sir.

I can't be more grateful, I pay my tuition fee by myself, and other websites charge me a few hundred dollars which I can't afford this point. I would like to pay you this when I become an RN. Thank you very much T.T

this is amazing and i like that its a human teaching me in real time from a board. thankyou!! vet nursing student from toronto!

You’re the best I swear sending all my love thank you ❤️❤️❤️❤️

This was wonderful!! How you explained the Na+ K+ pump and everything else. Thanks a lot sir ❤

u don't know how much u helped me before my final exam all my support to u guys

tbh I really wish my instructor discussed this the way you do. Thank you, Dr. Mike, you saved me.

That’s truly the best explanation ever! Thank you!

You are SO Good. Making something complex, more understandable.

This is my third time taking A&P and I'm sure I'll be here again in a year when I have to take it again but I've never understood mechanisms with such ease until your videos! Thank you so much from health profession students everywhere:)

Thank you Mike such a beautiful presentation.

Previous explanations have lost me a few minutes in, and left me thinking I’ll just never ‘get’ it. This makes absolute sense now, thank you

Great explanation! On another note, the calcium channel yields more calcium inside by triggering the calcium-induced-calcium-release through the sarcoplasmic reticulum. This maintains the plateau at phase 2 of the the action potential.

These videos help so much. Thank you

You just saved my life with this video 🦸🏽‍♂️🖤🖤🖤

Thank you a million times for this video. God bless you sir

You are so good Dr Mike, you made me understand this topic❤❤

I'm so glad I found you guys!!!!!!

Simple and easy. THANK YOU!

I've been reading about this and has been hard for me to understand. But after watching your video it has been so easy to get the concept. Please don't get tired of making our studies easier. Be much blessed

It was amazing, the best explanation ever , thank you

Amazing explanation. Studying for nursing school finals and this made an insane amount of sense!

I love your videos, I aspire my lectures to be as clear and precise as yours

Love you bro thanks for these videos. My physiology course instructor is terrible. Our entire grade is based on 6 exams that are all essay-based critical thinking questions. Your videos help me understand the concepts to answer those correctly.

Man, excellent lesson! Helped a lot. From a med student from Brazil 🇧🇷

Best explanation I have heard till now thank u sir

You are a true conceptual lecture.thank you sir

100 % even a small kid can understand by your explanation. Loved it guys

Great video and perfect explanation! Easy to follow. Thank you soooo much.Well done!

Short and amazing to understand the topic thoroughly 😊

Amazing explanation! Really helps in preparation of my physiology exam. Although I do wish you also explained action potential of the pacemaker but there is a lot of similarities in the understanding of each phase. Can't thank you enough.
