WebJun 28, 2013 · Excitability is the knack of cardiac cells to respond to a suitable amount of stimuli and produce an electric potential, also called electrical impulse. This electrical impulse spreads across the heart, causing it to beat. A single heart beat consists of two components, a systole and a diastole. WebAutomaticity is an intrinsic property of some types of cardiac tissues, like the nodes and the conducting fibers. Automatic cells are characterized by the appearance, during diastole, of a slow depolarization which is capable of reaching threshold and generate an action potential. WebAll adult cardiac myocytes can respond to electrical stimuli and conduct action potentials, but the working cells of the atria and ventricles generally lack automaticity … Arnold M.
