We wish to call attention to the use of methoxamine hydrochloride (Vasoxyl)1 in the treatment of paroxysmal supraventricular tachycardia. Not only is this drug effective in arresting the tachycardia, but, because of its powerful pressor action,2 it is especially useful in cases complicated by vascular collapse, a frequent occurrence.3 The mechanism of action is believed to be a reflex vagal effect following carotid sinus pressure elevation.

The first case is one of nodal tachycardia and the second, one of auricular tachycardia.
