OBJECTIVE: To determine the location for catheter electrode of intra-esophageal atrial pacing. METHODS: The catheter load was placed at a length eleven times that of the modified proportional unit of middle finger for intra-esophageal atrial pacing to stop the supraventricular tachycardia of 21 patients. RESULTS: Ninteen of them showed remarkable effect and 2 were effective. Tachycardia of all the patients was stopped, symptoms and signs such as chest distress, palpitation relieved and the blood pressure normalized. CONCLUSION: This is an accurate localization, rapid, convenient method with remarkable effects, it is a new way in rescuing supraventricular tachycardia patients.
