Who explains the conduction of the cardiac system?

Dr. Mike provides explanations on simplenursing.com.

The SA node acts as the heart's pacemaker.

Heart muscle cells shift from negative to positive charge.

The SA node is situated in the Atria.

Dr. Mike from simplenursing.com emphasizes the importance of understanding the cardiac system's conduction, highlighting the interconnected heart muscle cells that transition from negative to positive charges during depolarization for effective muscle contraction.
The SA node, situated in the Atria, plays a pivotal role as the heart's pacemaker, maintaining a sinus rhythm of 60 to 100 beats per minute by orchestrating the transition of charges within the Atrial muscle, a fundamental process for heart contraction.

The heart muscle cells are interconnected with gaps between them, transitioning from a negative charge to a positive charge during depolarization, essential for muscle contraction.
The Sinoatrial (SA) node, located in the Atria, acts as the heart's pacemaker, setting the sinus rhythm at 60 to 100 beats per minute. This specialized tissue transitions from a negative to a positive charge, initiating a wave of positive charge through the Atrial muscle, crucial for heart contraction.
