An electrical impulse is a surge of electricity, that is, a large flow of electrons or charged particles occurring seemingly spontaneously after experiencing a stimuli.
Several examples of electrical impulses include:
- Within the heart, an electrical impulse is used to cause beating, and these can be imitated in a pacemaker. Similarly a defibrillator uses a sudden electrical impulse to jump start the heart
- The nervous system works by a series of electrical impulses to and from the brain that stimulate muscles and other organs
