Excitation theory is a misattribution of arousal.

Zillman's Excitation Transfer Effect http://doctordigger.blogspot.com/2005/07/zillmans-excitation-transfer-effect.html

Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Heart excitation originates in the sino-atrial node.
