Cardiac Action Potentials Part 1: Review of Action Potentials

An introduction to the action potentials that occur in the heart. First, I briefly review how action potentials are changes in voltage over time and this ability to change voltage over time is set up by the Na/K ATPase as well as voltage-dependent channels. I then describe how the different voltage-dependent channels in auto-rhythmic cells and cardiac muscle cells create their respective action potentials.

I am currently starting a Masters project on modelling atrial fibrillation using cellular automata. As a physics student I have found this video incredibly helpful! Thank you.

Great lesson, however, it's hard to see the images, where can I get these pages?

Hello! This is has been a very helpful video! I was wondering if the diagram that you show in the video is available for download. I have a watched a few of your other videos and it was helpful to print off the schematic and write in notes while watching the video.

Thankyou - diagram looked confusing but very well explained :-)
