Pacemaker Cells of the Heart | Cardiology

In this video, Dr Mike discusses how pacemaker cells, like the SA node and AV node create different action potentials compared to cardiomyocytes (heart muscle cells).

Man you are a legend, i hope u live a life full of happy and joy, u deserve to be called a doctor

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.

the way you explain things makes me love to study more stuff, so thank you for your legendary videos and
keep going man. all respect from Algeria

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

[crushhurts]

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

[deekircher]

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

[amyzhao]

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

[chochee]

Understanding this for the first time!

[virgyb]

Thank you so much Dr. Mike!!!! Wish you were my professor!

[libruce]

i love u much you’re really solving my problem and saving my gpa

[luckydesilva]

Thank you so much and well explained .

[emmablunden]

Thank you that was very helpful.

[azadjehani]

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

[adeyemijohnson]

What type of questions can be asked from your lectures?

[Dr.Sara]

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

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 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.

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

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?
