<unk>  (also referred to as clinical<unk>  , or<unk>  is the science of the mechanisms, functions, and performance of the electrical activities of specific regions of the heart.
The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the myocardium<unk>  muscle).  The myocardium contracts after stimulation.  It is the ordered stimulation of the myocardium that allows efficient contraction of the heart, thereby allowing blood to be pumped throughout the body.
