Heart activity starts and is controlled by spontaneous generation of electrical impulses. The heart epitomizes an admirable pump that tirelessly pumps the blood into circulation via regular contractions. Each contraction of the heart is triggered by an electric impulse, which is normally generated spontaneously in a specialized cluster of cells of the heart (pacemaker). Electrical impulse passes Read more
