THE CARDIAC CONDUCTION SYSTEM

In this video we will look at how the action potential spreads from the sinoatrial node to all regions of the heart in coordinated manner. We will also look at how the electrical activity of the cardiac conduction system aligns with the mechanical phases of the cardiac cycle.

 

Before watching this video, you should have an understanding of “The cardiac cycle”, “The cardiac action potential” and “Excitation-contraction coupling”.
