Sympathetic activation, mediated by the -ARs-Gs-adenylyl cyclase-cAMP-protein kinase A (PKA) signaling pathway, activates and phosphorylates LTCCs, increasing inward Ca 2+ current ( 2+ release from SR, which in turn increases cardiac contractility ( 2+ removal from cytosol, thus improving cardiac relaxation
