我们对1例顽固室上性心动过速(SVT)患者进行电生理检查后,经导管电灼房室结治疗,取得满意效果。现报道如下。患者,女,56岁。因反复发作SVT2年余,药物疗效不佳入院。体检:心界不大,无杂音,HR63次/分,律整。ECG:窦性心律,电轴左偏(-20)。心脏X线摄片、二维超声心动图检查均正常.心内电生理检查显示左侧旁路参与的顺向型房室折返性心动过速。在心房调搏过程中,偶有预激图形出现,无房室结双径路及多条旁路。于1990年6月4日行房室结电灼术。使用日本
We conducted a electrophysiological examination of 1 patient with stubborn supraventricular tachycardia (SVT) and achieved satisfactory results by catheterization of atrioventricular node. Report as follows now. Patient, female, 56 years old. Due to recurrent SVT2 years of age, poor efficacy of the drug admission. Physical examination: little heart, no noise, HR63 times / min, law and order. ECG: sinus rhythm, left axis deviation (-20). Cardiac X-ray and two-dimensional echocardiography were normal, and electrophysiological examination of the heart revealed a forward atrioventricular reentrant tachycardia with a left bypass. In the atrial pacing process, occasional pre-excited graphics appear, no dual atrioventricular junction path and multiple bypass. On June 4, 1990, atrioventricular nociception was performed. Use Japan
