Electrical impulses that occur naturally and are generated by certain cells, such as neurons and muscle cells, without external stimulation.
SA Node
The sinoatrial node is a collection of cells located in the heart's right atrium, responsible for determining the heart's rhythm by creating electrical signals.
AV Node
The atrioventricular node, a part of the electrical conduction system of the heart that coordinates the top of the heart. It plays a crucial role in the control of the heart rate.
Purkinje Fibers
