Abstract: Objective:To explore effect for isoproterenol rising detection rate of paroxysmal supraventricular tachy‐cardia by transesophageal atrial pacing (TEAP) .Methods :A total of 85 patients with suspected PSVT attack history received routine TEAP ( basic stimulate ) ,for those failed to evoke PSVT ,they received additional intravenous infusion of isoproterenol to make heart rate rise to 120 beats/min ,then TEAP was repeated .Results :Routine TEAP evoked PSVT in 29 cases (34.1% ,29/85) ;among the remaining 56 cases un - evoked PSVT ,after intravenous infusion of isoproterenol PSVT was evoked in 54 cases (96.4% ,54/56) by TEAP ,and this detection rate was significantly higher than that of routine TEAP (96.4% vs .34.1% , P = 0.039) .Conclusion :Intravenous infusion of isoproterenol can greatly raise the detection rate of paroxysmal supraventricular tachycardia by transesophageal atrial pacing .
