Propranolol is a beta-blocker medication that blocks the beta-1 receptors in the heart, resulting in a decrease in heart rate, which is a negative chronotropic effect. It also causes a decrease in contractility, which is a negative inotropic effect, and a decrease in conduction velocity, which is a negative dromotropic effect.
