Beta 1 receptors - - Heart: increase cardiac rate (chronotropic) and increase force of contraction (inotropic) Juxtaglomerular cells: increase renin release Isoproterenol - - Beta 1 prototypic agonist; nonselective, used for bronchodilation (beta 2) and cardiac stimulant (beta 1) Metoprolol - - Beta 1 prototypic antagonist Heart: reduces rate and force of contraction, inhibits impulse conduction Kidney: suppresses renin secretion
