我们最近在一例预激综合征(预激征)正向型房室折返性心动过速(OAVRT)见到于室性早搏后经希司束下传的 V 波前无明显 H 波,兹将电生理检查资料报道于下,并对这一特殊的机制进行探讨。病例介绍患者女性,11岁。以反复发作心动过速6年,药物治疗不满意,在门诊经食管心房调搏检查诊断为 B 型预激征合并 OAVRT,要求手术治疗于90-10-22入院。体格检查、胸片及超声心动图均未见异常。4天后作心内电生理检查。术前一个月内未用过抗心律失常药物,检查在
We recently in a case of pre-excitation syndrome (pre-excitation) positive type atrioventricular reentrant tachycardia (OAVRT) seen in premature ventricular contractions after descending Histone beam V waves without obvious H waves, will hereby Electrophysiological data are reported below, and this particular mechanism is explored. Case Presentation Patient Female, 11 years old. To recurrent tachycardia for 6 years, drug treatment is not satisfied with the diagnosis of pre-esophageal atrial pacing in the clinic diagnosed as type B pre-excitation merger with OAVRT, requiring surgical treatment of 90-10-22 admission. Physical examination, chest X-ray and echocardiography were normal. 4 days after the intracardiac electrophysiological examination. Anti-arrhythmic drugs have not been used within one month before surgery
