摘要
目的:探讨异丙肾上腺素提高食管心房调搏术(TEAP)对阵发性室上性心动过速(PSVT)检出率的作用。方法:在85例怀疑有PSVT发作史患者行常规TEAP(基本刺激),对于未能诱发PSVT者,静脉滴注异丙肾上腺素使心率增快至120次/min,再重复TEAP。结果:常规食管心房调搏术诱发PSVT 29例(34.1%,29/85),未能诱发PSVT的56例加静脉滴注异丙肾上腺素,再重复TEAP,诱发PSVT54例(96.4%,54/56),这检出率显著高于常规TEAP的检出率(96.4%比34.1%,P=0.039)。结论:静脉滴注异丙肾上腺素能大大提高食管心房调搏术对阵发性室上性心动过速的检出率。
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 .
