在临床电生理检查时,常见房室结前传双径路,多径路亦不少见,笔者遇到1例房室结前传四径路同时具备有逆向双径路伴室上性心动过速(SVT)患者。现报告如下: 患者女性,21岁。困发作性心悸8年加重1年入院。心动过速发作时心率最快200bpm,用物理方法和药物均能终止发作。体检和心电图均正常。经股静脉穿刺(左、右)分别插入4根6F2～4极导管置于高位右房(HRA)、右房下外侧(LLRA)、希氏束(HBE),右室心尖部(RVA)。以食管电极代表左房 In the clinical electrophysiological examination, common Atrioventricular Node Pathways, multi-pathways are not uncommon, I encountered a case of anterior chamber junction pathways at the same time have four pairs of reverse dual pathways with supraventricular tachycardia (SVT) patients. The report is as follows: Patient Female, 21 years old. Sleepy onset of heart palpitations 8-year exacerbation of 1-year admission. Tachycardia heart rate when the fastest 200bpm, with physical methods and drugs can terminate the attack. Physical examination and ECG are normal. Four 6F2 ~ 4 catheters were inserted through the femoral vein puncture (left and right) into the right atrium (HRA), the right atrium (LLRA), His bundle (HBE) and the right ventricular apex (RVA). The esophageal electrode represents the left atrium
