Supraventricular tachycardia can be caused by multiple atrioventricular nodal pathways or atrioventricular accessory pathways. Herein, we report the case of a patient who was diagnosed with an orthodromic atrioventricular reentrant tachycardia that was caused by an unusual combination of quadruple atrioventricular nodal pathways and an atrioventricular accessory pathway. Radiofrequency catheter ablation of the accessory pathway successfully eliminated the arrhythmias and the patient's symptoms. Careful analysis of complete electrophysiologic studies can help in the diagnosis of such rare clinical presentations.
室上性心动过速可由多条房室结通路或房室旁路引起。在此，我们报告一例患者，该患者被诊断为顺向型房室折返性心动过速，其由四重房室结通路和一条房室旁路的异常组合所致。对旁路进行射频导管消融成功消除了心律失常及患者症状。对完整电生理研究进行仔细分析有助于诊断此类罕见的临床表现。
