we conclude that epinephrine , dopamine , and dobutamine are capable of producing cardiac arrhythmias in vagotomized and nonvagotomized thiamylal-halothane anesthetized dogs and that bilateral vagotomy decreases the dosage of epinephrine , dopamine , and dobutamine required to produce cardiac arrhythmias .
