Electrophysiology Lectures

This is a nine-part video lecture describing the electrophysiology of the heart.  There are links to the videos as well as the PowerPoint presentations that you can download for free.  Please let me know what you think of them!  I love getting feedback.

​

Part 0 – Cardiac Electrophysiology - 0 Fundamentals

In this lecture we'll be going over some basic biology to get you ready for cardiac electrophysiology.

Part 1 – Cardiovascular Electrophysiology 1 - Movement through the membrane

In this lecture we're going to describe how different ions are able to move in and out of the cell.

Part 2 – Cardiovascular Electrophysiology 2 - Electrical Flow In The Heart

In this lecture we're going to talk about how a hunk of meat in your chest can generate electricity.

Part 3 - Cardiovascular Electrophysiology 3 - Action Potential of the Myocytes

In this lecture, we're going to go over the pattern of how ions move in and out of the cell in a regular, repeating pattern - called the Action Potential.

Part 4 - Cardiovascular Electrophysiology 4 - Action Potential of the Pacemaker Cells

In this lecture we're going to describe how 'pacemaker' cells can spontaneously depolarize without anything stimulating them externally.

Part 6 - Cardiovascular Electrophysiology 6 - Excitation Contraction Coupling

In this video we're going to go over how depolarisation initiates contraction of the heart.

Part 7 - Cardiovascular Electrophysiology 7 - ANS Influence on the Heart

In this lecture we cover how our body changes the rate and strength of our heart, going from external stimuli to the actual ionic changes that take place in the myocardial cells.  If I yell 'boo!', your heart speeds up.  Why?  How?

Part 8 - 8 Paramedic Pharmacology – Antidysrhythmics

In this final lecture, we review cardiac antidysrhythmics with a fairly introductory discussion of how they are classified and how they work.
