How is the action potential conducted inside the heart?

Dr Mona December 17, 2023

The action potential in the heart is conducted through the myocardial conducting cells. It starts from the SA node, spreads through the atria, reaches the AV node, then travels through the atrioventricular bundle, divides into left and right bundle branches, and finally spreads through the Purkinje fibers.
