95例均为房室旁路引起的有症状的心动过速患者。年龄20～78(50±10)岁。5例伴扩张性心肌病,2例伴肺部疾患,2例有严重高血压,1例有爱勃斯坦畸型。将5～6根电极导管经由颈内静脉、左或右股静脉插入以对心房和心室行程序起搏以及旁路定位。旁路位于记到旁路电位处,或最早心室及心房激动点处。前29例以直流电消蚀,消蚀导管为6F四极导管。消蚀左侧旁路时,导管经房间隔穿刺送入左房,并将远端电极抵住二尖瓣环。消蚀右侧旁路时,导管的远端电
All 95 cases were symptomatic tachycardia caused by atrioventricular bypass. Age 20 ~ 78 (50 ± 10) years old. 5 cases with dilated cardiomyopathy, 2 cases with lung disease, 2 cases with severe hypertension, 1 case with Aistenestectomy. Five to six lead catheters are inserted via the jugular vein, left or right femoral vein for pacing and bypass positioning of atrial and ventricular procedures. Bypass is located at the bypass potential, or the earliest ventricular and atrial activation points. The first 29 cases of DC erosion, ablation catheter for the 6F quadrupole catheter. Eradicate the left bypass, the catheter puncture through the atrial septal into the left atrium, and the distal electrode against the mitral valve annulus. When the right bypass is ablated, the distal end of the catheter is electrically energized
