Eight patients with atrial flutter (AF) and rapid atrial tachycardia (AT) (5 common AF, 1 uncommon AF and 2 AT) were treated with transesophageal atrial pacing (TEAP). In 5 patients no antiarrhythmic agent was used during this study, and in 3 patients procainamide was administrated intravenously. Conversion to sinus rhythm was successfully achieved in 7 patients (5 common AF and 2 AT). Two patients were converted to sinus rhythm immediately after pacing, and transient atrial fibrillation was induced before conversion to sinus rhythm in 5 patients. TEAP failed to terminate the arrhythmia in 1 patient with uncommon AF. Administration of procainamide reduced the atrial rate in 2 common AF and 1 AT, which were successfully converted to sinus rhythm by TEAP, but induced a rapid ventricular response in 2 patients, one of whom also developed hypotension before conversion. No significant complication due to TEAP was observed in this study. In conclusion, TEAP is a noninvasive method with fewer complications and has nearly the same high efficacy for converting AF and rapid AT to sinus rhythm as DC cardioversion or transvenous atrial pacing.
8例心房扑动(AF)和快速房性心动过速(AT)患者(5例常见AF、1例不常见AF和2例AT)接受了经食管心房起搏(TEAP)治疗。本研究期间,5例患者未使用抗心律失常药物,3例患者静脉注射了普鲁卡因胺。7例患者(5例常见AF和2例AT)成功转为窦性心律。2例患者起搏后立即转为窦性心律,5例患者在转为窦性心律前诱发了短暂性心房颤动。1例不常见AF患者TEAP未能终止心律失常。普鲁卡因胺给药使2例常见AF和1例AT的心房率降低,这3例患者经TEAP成功转为窦性心律,但2例患者出现快速心室反应,其中1例在转复前还出现了低血压。本研究未观察到TEAP引起的明显并发症。总之,TEAP是一种并发症较少的非侵入性方法,对于将AF和快速AT转为窦性心律,其疗效与直流电复律或经静脉心房起搏几乎相同且很高。
