During contractions that pump blood throughout the body, contractile cells carry out impulses. The conduction system of the heart is made up of autorhythmic myocardial conducting cells, which make up 1% of all cells.
The natural pacemaker of the heart is the sinus node. In the right atrium's upper portion, there is a small collection of specialized cells (upper chamber of the heart). The electrical impulses that cause your heart to beat are created by it. A cardiac chamber that receives an electrical impulse or signal contracts.
The walls of the heart are composed of a network of specialized muscle cells. These muscle cells communicate with the other heart muscle cells, prompting the other cells to contract. The cardiac conduction system is the name given to this collection of muscle cells.
