What are cardiovascular effects of isoproterenol (b1,b2) non selective?

Produces intense stimulation of the heart to increase its rate and force of contraction, causing increased cardiac output useful in the treatment of atrioventricular block or cardiac arrest. dilates the arterioles of skeletal muscle (β2 effect), resulting in decreased peripheral resistance. may increase systolic blood pressure slightly because of its cardiac stimulatory action reduces mean arterial and diastolic blood pressure
