Dr Mike you have no idea how much your videos help me with my studies. The way you explain things so thoroughly really consolidates everything & you actually make it all make sense and the diagrams really help too. Terrific job. Dont ever stop!! THANK YOU !!
Just rewatching a few of your videos on Cardiac activity to prepare for an exam today and I feel ready now!! Thank you so much for the incredibly helpful content!!!
This was absolutely amazing. The relief I got throughout the video because it was becoming easier to understand!!!! How exciting!!* Thank you, Dr. Mike!! Keep it up!
Hello Dr. Mike. Patient here, not a student. So this is how my pacemaker performs LBBP, yes? I am due, in a few weeks, for my first Echo TTE post installation and am hopeful that my EF has improved. The pacemakers accelerometer has done a great job of sensing my body activity, or lack thereof. Currently biking 4x per week and lifting weights 3x per week. Great videos. Thanks, Tom
I was trying to understand why one would give calcium in a-fib after giving Cardizem and I was told it was for the "extra squeeze". So I guess the calcium channel blocker slows the influx of Ca++ and therefore the fast rate but the extra calcium administered helps the contractile nodes to still squeeze properly. Is that correct?
Hey Dr. Mike, I was wondering if the pacemaker cells in the ventricles have different action potentials? Do they have different ions traveling through different phases or are all PM cells firing the same. I’ve looked all over the net and can’t find anything about it. Thank you!!
Dr. Mike thank you so much for your explanation! It’s very straight to the point while going through a lot of details! I just had a question while watching the video. So if I understood correctly, depolarization occurs because the influx of calcium inside the cell through the calcium channel stops because the channel closes and the potassium channel opens which allows potassium to leave the cell. There’s also a refractory period in which calcium slowly goes in to the cell, and due to the slow influx of calcium and I’m assuming slow efflux of potassium the plateau occurs? So does the release of calcium from the sarcoplasmic reticulum during depolarization not affect the depolarization? I remember in the beginning of the you mentioned the charge difference is across the membrane not within the entire cell and I was wondering if it had to do with that. Thank you!

Thanks!
I really appreciate you for making these videos, you are the only reason I passed a&P1
Medical student here! Just found this channel and it's amazing. The best thing is that the videos are short and easy to understand.
I've been following Dr. Mike for a while and I'm glad to learn from him.
I'm also a medical student.
Can we learn together?
Literally couldn't understand this topic, but your video made it so clear, thanks man.
Your videos are so helpful.Studying for physiology exam at Masters level. Easy to follow and understand.
You’re the only person on this app that actually makes senseeee thank youuu💗
Just rewatching a few of your videos on Cardiac activity to prepare for an exam today and I feel ready now!! Thank you so much for the incredibly helpful content!!!
Iam impressed with your teachings,iam from Tanzania, peacefully country
Never stop uploading. They are really helpful for us learners! Sincerely Appreciate your efforts
This was absolutely amazing. The relief I got throughout the video because it was becoming easier to understand!!!! How exciting!!* Thank you, Dr. Mike!! Keep it up!
I was literally just revising this topic for my exam tomorrow. Thank you!
You are the goat Dr Mike, only reason im making it through a&p 2
Simple but to the point. Many thanks for making those complex topics much more easier to understand.❤❤
Dr Mike, you are amazing. Such a good method of teaching, making it so easy. Thank you.
You're very welcome!
thank you so much dr. Mike , wish our instructors were capable to explain this way instead of screaming all the time.
I got a HD in biomed because of your channel! THANK YOU :)
A brilliant video on action potential.
Hats off🎉
this video is a solid 10/10 THANKS FOR THIS GREAT LECTURE
thank you!! this is very helpful for my CVS exam!!
Thank you your videos are great and help so much with my Physiotherapy studies
Amazing explanation, i really like the clinical correlation that you've mentioned at the end
Thank you so so much!! your a very good person Dr Mike , In a few hours pulled together so much information .
You are very welcome
Yes,You were born to be a teacher!
Im a veterinarian student i really enjoyed this vedio thanks dr maike ❤
Glad you enjoyed it!
Thanks Dr.Mike for this awesome tutorial 🙏
Really really appreciate your videos. It makes so much more sense
thank you dr mike, very helpful
Wow man that's great I really now understood this

Very useful. Can you use this model to explain Afib in another video?
Great video.
U are so awesome 🤩 from iraq i love ur videos
Iam impressed with his teaching iam from Tanzania ,peacefully country
Thank you !
