Question | Answer |
the pacemaker; highly specialized, neurological tissue impeded in the wall of the right atrium; responsible for initiating electrical conduction of the heartbeat, causing the atria to contract and firing conduction of impulses to the AV node | sinoatrial (SA) node |
neurological tissue in the center of the heart that receives and amplifies the conduction of impulses from the SA node to the bundle of His | atrioventricular (AV) node |
neurological fibers extending from the AV node to the right and left bundle branches that fire the impulse from the AV node to the Purkinje fibers | bundle of His |
fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract | Purkinje fibers |
resting; resting state of a myocardial cell | polarization |
change of a myocardial cell from a polarized (resting) state to a state of contraction (de = not; polarization = resting) | depolarization |
recharging of the myocardial cell from a contracted state back to a resting state (re = again; polarization = resting) | repolarization |
regular rhythm of the heart cycle stimulated by the SA node (average rate of 60–100 beats/minute) (see Fig. 5-11) | normal sinus rhythm (NSR) |
