In this video, we will explore cardiac conduction system, a network of specialized cells within the heart that coordinates the rhythmic contraction and relaxation of the heart muscle. We will discover the role of each component of the system, including the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers, in ensuring the effective pumping of blood throughout the body. The video also touches on common arrhythmias that can result from disruptions in the system and potential treatment options.
