The heart is a pump made of muscle tissue. Its pumping action is regulated by electrical impulses.
How does the heart's electrical system work? · Conducting cells carry your heart's electrical signal. · Muscle cells enable your heart's chambers to contract, an action ...
The third order of electrical influence of the heart is derived from the vagus nerve as the other peripheral organs form. Function[edit]. Action potential generation[ ...
The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the ...
A network of specialized muscle cells is found in the heart's walls.

The American Heart Association explains that arrhythmia refers to any change from the normal sequence of electrical impulses, such as atrial ...
Sequence of Cardiac Electrical Activation. conduction velocities in the heart. The action potentials generated by the SA node spread throughout the atria ...
Thus, the electrical signals cause the mechanical pumping action of the heart.
Electrical impulses from your heart muscle (the myocardium) cause your heart to beat (contract). This electrical signal begins in the sinoatrial (SA) node, located ...
