Briefly describe the pathway that the electrical conduction pattern in the heart follows.

Answer :

Final answer:

The electrical conduction pattern in the heart follows a specific pathway called the cardiac conduction system, starting from the SA node and ending at the Purkinje fibers.


Explanation:

The electrical conduction pattern in the heart follows a specific pathway, known as the cardiac conduction system. This system starts with an electrical signal originating from the sinoatrial (SA) node located in the right atrium. The signal then travels to the atrioventricular (AV) node, located between the atria and the ventricles. From there, it spreads through the bundle of His and its branches, known as the bundle branches, which extend into both ventricles. Finally, the signal reaches the Purkinje fibers, which stimulate the ventricles to contract.
