title: Important sinus bradycardia occurring after intravenous norepinephrine for terminating tachyarrhythmias associated with shock.
abstract: Using norepinephrine given intravenously in 10 patients with tachyarrhythmias associated with cardiogenic shock, an important sinus bradycardia was always produced, indicating an evident vagal stimulation as underlying mechanism of the termination of arrhythmias.
