1病例报告病例1,女,26岁,因“因阵发性心悸10年,加重2个月”就诊。心悸发作时心电图示室上性心动过速,入院后行心内电生理检查:心室S1S1280ms出现文氏传导,心房S1S2500/400ms出现跳跃性传导,未诱发心动过速,予异丙基肾上腺素静点后行心房刺激于S1S1220ms诱发心动过速。心内传导顺序呈向心性,希氏束的逆传心房波最为提前,诊断房室结折返性心动过速,房室结双径路。采用下位法,RAO30°投照下,于His与CSO中下1/3处标测到小A大V波,A波碎裂处在温控55℃25W下放电消融,10s内出现交界性心律,继续放
1 Case report Case 1, female, 26 years old, because “due to paroxysmal palpitations 10 years, increased 2 months ” treatment. Palpitation onset of ECG showed supraventricular tachycardia, cardiac electrophysiology after admission line: ventricular S1S1280ms appear Venturi conduction, atrial S1S2500 / 400ms appear jump conduction, did not induce tachycardia, isoproterenol static point Atrial fibrillation after S1S1220ms induced tachycardia. Heart conduction order was concentric, His bundle beam reverse the most advanced atrial wave, diagnosis of atrioventricular nodal reentrant tachycardia, atrioventricular node dual pathway. Using the lower method, RAO30 ° projection, in the His and CSO in the next 1/3 marked the small A large V wave, A wave fragmentation in the temperature control 55 ℃ 25W discharge ablation, border within 10s arrhythmia , Continue to put
