Source sentences:
text: The SA node kicks off the normal cardiac cycle, generating an electrical impulse that travels right through the walls of the atria, causing them to contract.
text: A specialized group of cells located in the upper chamber (atrium) of the heart, acts as a pacemaker that generates an electrical impulse.
text: A cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural pacemaker of the heart), is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers (the upper, or atria and/or the lower, or ventricles) to contract and therefore pump blood; by doing so this device replaces and/or regulates the function of the electrical conduction system of the heart.
