经食管心房起搏治疗心房扑动的方法研究及临床应用评价

Methodologic Study and Clinical Application of Transesophageal Atrial Pacing in Treatment of Atrial Flutter

本文采用经食管心房起搏(TEAP)技术治疗了40例患者的46次心房扑动(AF)发作。结果27例Ⅰ型AF患者的34次发作均治疗成功,13次直接转为窦性心律,余21次转为房颤(Af)后心室率显著减慢(P<0.0005),其中,14次在6小时内自行恢复为窦性心率。13例Ⅱ型AF患者中仅1例F波规则者转为持续性Af。文中对使用TEAP转复Af的有关临床问题作了详细讨论。

Transesophageal atrial pacing(TEAP) conversion was performed in 46 episodes ofatrial flutter(AF) in 40 consecutive patients. Successful rhythm conversion was achi-eved on 34 occasions in 27 patients who had type Ⅰ of AF, the AF rhythm was rever-ted immediately to sinus mechanism in 13 instances and to atrial fibrillation(Af) in21 instances and there was significant decrease of heart rate(P<0.000 5) after Af.Among those who experienced Af, the rhythm was spontaneously reverted to sinusmechanism. within 6 hours on 14 occasions. But only one who had regular F in the 13patients. with type Ⅱ of AF was converted into persistent Af. Detailed problemsrelevant to clinical application of TEAP conversion for AF were discussed.
