Termination of paroxysmal supraventricular tachycardia with a single oral dose of diltiazem and propranolol.

abstract：:Prenalterol, a beta-adrenergic agonist, was given to nine patients with angiographically proved coronary artery disease. Subjects were studied during chronic beta-adrenergic blockade. The adequacy of blockade was assessed by the exercise heart rate response and by plasma concentrations of blocking agents. After increm...
