Which beta-agonist is nonselective and increases cardiac output and bronchodilation?

Nonselective beta-adrenergic stimulation increases both cardiac output and bronchodilation. Isoproterenol fits because it activates beta-1 receptors in the heart, raising heart rate and contractility to boost cardiac output, and beta-2 receptors in the airways, causing bronchodilation. The other agents aren’t beta-agonists: prazosin blocks alpha-1 receptors; detomidine and romifidine are alpha-2 agonists with sedative and different cardiovascular effects. So the one that matches both increased cardiac output and bronchodilation through beta-receptor stimulation is isoproterenol.
