改良中指同身寸度量食道心房调搏导管深度中止室上性心动过速的临床应用

Clinical Application of Modified Proportional Unit of Middle Finger to Determine the Depth for In tra-Esophageal Atrial Pacing to Stop Supraventricular Tachycardia

目的：为了解决食道心房调搏导管电极一次到位问题；方法：采用度量改良中指同身寸，并乘以１１倍，作为导管电极长度起搏心脏，中止２１例室上性心动过速患者；结果：显效１９例，有效２例，心动过速均被中止，胸闷、心悸、血压下降等症状和体征均恢复正常；结论：此法定位准确，抢救患者迅速、方便、显效，为抢救患者开创了一种新途径。

To determine the location for catheter electrode of intra-esophapeal atrial poeing.Methods: The catheter load was Placed at a length eleven times that of the modified proportional unitof middle finger for intra-esophapeal atrial poeing to stop the supraventricular tachycardis of pa tients. ResultS: Ninteen of them showed remarkable effect and 2 were effective. Tachycardia of allthe patients was stopped, symptoms and signs such as chest distress, palpitation relieved and the bloodpressure normalized. Conclusion: This is an accurate localization, rapid, convenient method withremarkable effects, it is a new way in rescuing supraventricular tachycardia patients.
