Title: [Effect of intravenous atropine on the induction of paroxysmal supraventricular tachycardia].
Abstract: Sixty nine patients with the history of paroxysmal supraventricular tachycardia (PSVT) or possible history of PSVT failed to have PSVT provoked by transesophageal atrial pacing (TEAP). After intravenous administration of 0.02 mg/kg atropine, 42 patients had PSVT provoked during the second TEAP. The electrophysiologic parameters showed that atropine could increase the inducibility of PSVT. The main effect was to decrease the anterograde AV node effective refractory period (ERP) or fast pathway ERP and provide an available condition for the reentry of impulses. The conclusion is that atropine could definitely increase the diagnostic value of TEAP.
