本文报告了25例预激综合征的BSM,对ACP进行了试探性定位诊断,并与常规ECG定位进行了对比。常规ECG根据Rosenbaum分型仅能大致提示左室或右室的预激,但定位太粗糙且不可靠,对手术治疗缺乏指导意义。按Callagher对Δ波起始向量分型,与BSM符合者16例,基本符合者7例,不符合者2例。BSM可提供常规ECG不能提供的一些资料,对ACP的定位更准确可靠。作为术前初步定位诊断的无创伤性检查,具有相当重要的临床意义。
This article reports 25 cases of pre-excitation syndrome of BSM, ACP exploratory positioning diagnosis, and compared with the conventional ECG positioning. Routine ECG according to Rosenbaum classification can only be roughly prompted left ventricular or right ventricular pre-excitation, but the positioning is too rough and unreliable, the lack of guidance for surgical treatment. According to Callagher, the initial vector of Δ wave was classified, which was consistent with BSM in 16 cases, basically consistent with 7 cases and nonconformities in 2 cases. BSM can provide some information that conventional ECG can not provide, more accurate and reliable positioning of ACP. As a preoperative diagnosis of noninvasive initial location, has a very important clinical significance.
