WebNormally at rest, as the electrical impulse moves through the heart, the heart contracts about 60 to 100 times a minute, depending on a person's age. Each contraction of the ventricles represents one heartbeat. The atria contract a fraction of a second before the ventricles so their blood empties into the ventricles before the ventricles contract. WebHeart rate is also regulated through the SERCA2 inhibitor phospholamban (PLB) which is a major target of adrenergic signaling ( Maclennan and Kranias, 2003 ). Thus a tightly controlled cycle of Ca 2+ entry and release precisely regulates beat to beat oscillations in cardiac cells. View chapter Purchase book Inherited Diseases of Ion Transport
