It's incredible how you can take complex processes and break them down so simply without dumbing it down. Physiology at uni is the total opposite. They spend quadruple the time explaining it and I only learn like quarter of what I do watching these. I suppose you have the advantage of being able to be paused and rewinded over and over again though! Thanks so much for putting out free educational content.

Simple and straight to the point. Thanks man. Really helpful

I’m really enjoying these videos and I was always told I am “bad at science”. I am now starting to like science

Your method of teaching is great. Your videos have made medical science so easy to understand. Loads of Thanks for each video

love Dr Mike's explanation thank you for making my study journey easier

it finally clicked thank you so much!!! love your videos

Incredible! Great explanation!

Understanding this for the first time!

Thank you so much and well explained .

Thank u sir 😊

U are amazing Sir😍😍 ... U made my day ... Great efforts keep making such videos😊😊

thx now I can understand AP in SA node and maybe can expline for my friends😅😅😅

Thannkkk youuuuuu🖤🖤

Thanks

اشهد ان لا اله الله . وان محمد رسول الله Thank you that was very helpful.

Amazing smart boy

Thaaaaank u so much

Do u think any maker to guide rotate sodium .calcium and potassium to drive depolarisation and repolarisation in out of pacemaker cell? All of insttuctor talk about potentiäl curve. Nobody clarify the chemical mechanism .thanks

Have you ever studied POTS? My daughter has SEVERE POTS - she was bedbound by 6yrs of age - her heart beats at 150-160bpm when standing still and getsmuchhigher if walking moving at all basically - making the bed sends it shooting up. She is on Ivabradine which works directly ontheSA node and has dropped the hr a bit but it is still really very high altho now she isn't bedbound but life is limited- she cannot attend school she is very tired and weneed to be very careful whta we do. I have been researching for 5 yrs and came across your videos - it is a neuro issue with the signals - just tryingto figure out if there's any new research done by peoplelike you..... people with POTShave to drink electrolytes with magnesium, calcium, sodium, potassium wondering ifthis is because of what you have descrbed vs what is generally accepted to be because it helps with blood volume.

I’m sorry I don’t understand the summary equal amounts must be entering and leaving over a period of a cycle. On the up slopes Na and Ca in, on the downslope K in?

Doctor just told me my heart rate has dropped to zero and that it wont work again, so basically only the pacemaker is what's keeping me alive. Do you have any reading material for people in my condition? Thank you!

At end of the circle, the cell is full of Ca+, how dose the next circle start with putting out Na+?

such a dank intro

During depolarisation the calcium channels are l type or t type?

Pulse

so is leaking channels a bad thing ?

It's like a mini heart within a normal heart

I don't know if you did this in order to make things simpler, but that's not how pacemaker cells work
