Transesophageal atrial pacing with relatively low current output and wide pulse duration has been recently reported. With this method supraventricular tachycardias can be successfully induced and terminated. In this study 23 episodes of spontaneous common atrial flutter (21 patients) were treated by rapid transesophageal atrial pacing (output of 16 Volts and pulse duration of 10 msec). Sinus rhythm resumption was obtained in 18 episodes (78.2%), directly after interruption of stimulation in 7 and following brief periods of atrial fibrillation in 11. All patients tolerated the procedure well with moderate discomfort; no complications were observed. Esophageal pacing offers a useful, rapid, minimally invasive, well tolerated method of terminating atrial flutter in the clinical practice.
