5例预激综合征病人,4例显性,1例隐匿性。5例电生理检查(EPS)均提示为多条房室旁道(MAAP),正确率为100％(5/5),经心外膜标测(ECM)证实为多旁道的4例,正确率为80％(4/5),经ECG提示为双旁路仅1例,正确率为20％。本文报告的5例MAAP中有4例EPS和ECM结论一致,手术后得到完全治愈,因此,结合ECG、EPS、ECM的定位结果综合判定,方能提高旁路定位的正确率。
5 cases of pre-excitation syndrome patients, 4 cases were dominant, 1 case of occult. Five cases of electrophysiological examination (EPS) were prompted for multiple paraventricular access (MAAP), the correct rate was 100% (5/5), confirmed by epicardial mapping (ECM) as a multi-channel 4 cases, The correct rate was 80% (4/5). Only 1 patient was double-biased by ECG, with a correct rate of 20%. In this paper, 4 out of the 5 MAAP cases were found to be consistent with EPS and ECM. After the operation, they were completely cured. Therefore, combining with the results of ECG, EPS and ECM, the accuracy of bypass positioning can be improved.
