治疗室上性心动过速(SVT)采用刺激迷走神经方法和药物治疗并不总是有效,近年来经食管心房调搏治疗 SVT 受到重视,本文报告这样一组病例.临床资料全组11例,其中房室结双径路折返,慢快型8例(AVNRT),预激伴正向性房室折返3例(AVRT).SVT 发作19次,均经刺激迷走神经方法和药物治疗无效,发作时间持续3小时至3天.食道调搏方法采取:①程控心房早搏刺激法(S_2法).若反复5次 SVT 未停止,改用②超速抑制法.结果19例次 SVT 发作,6例次由 S_2法终止,其余均由超速抑制法终止,合并心源性休
Treatment of supraventricular tachycardia (SVT) using stimulation of the vagus nerve method and drug therapy is not always effective, in recent years transesophageal atrial pacing for the treatment of SVT has been attention, this article reports such a group of patients.Clinical data of the whole group of 11 patients, of which Atrioventricular nodal dual path reentry, slow type in 8 cases (AVNRT), pre-excitation with positive atrioventricular retrograde in 3 cases (AVRT) .SVT attack in 19 times, both by stimulation of the vagus nerve method and drug therapy, the onset time 3 Hour to 3 days.Patients with esophageal pacing method adopted: (1) Stroke atrial premature beat stimulation (S_2 method) .If repeated 5 times SVT did not stop, switch to overdrive inhibition method.Results 19 cases of SVT attack, 6 cases by S_2 method Termination, the rest were terminated by speeding suppression, combined with cardiogenic Hugh
