Sinoatrial node ($SA$ node)

Vedclass · Answer

(B) The $SA$ node (Sinoatrial node) is a specialized patch of cardiac muscle fibers located in the right atrium. It acts as the natural pacemaker of the heart because it has the unique ability to generate action potentials without any external stimuli. This electrical impulse initiates the rhythmic contraction of the heart and maintains its rhythmic activity throughout life.

Which part of the heart is responsible for initiating and maintaining its rhythmic activity?
