The purpose of this study was to evaluate the usefulness of tomographic phase analysis in detecting the site of the accessory conduction pathway (ACP) in patients with Wolff-Parkinson-White (WPW) syndrome. Gated emission computed tomography and planar gated blood pool scintigraphy were performed in 20 patients with WPW syndrome, 14 with delta waves and six without delta waves (two intermittent types and four concealed types). The abnormal initial contractions in both planar and tomographic phase images were compared with the sites of ACPs confirmed by epicardial mapping and surgery. The atrioventricular ring was divided into eight segments on each side, and the identification of the initial phase in the segment in which the ACP was located, or that adjacent to it, was considered to be the correct diagnosis. In planar phase analysis, the abnormal initial phase was identified correctly in 8 of 14 patients (57%), whereas in tomographic phase analysis, the site of the ACP was detected in 12 of 14 patients (86%). Tomographic phase analysis can be a helpful adjunctive method in patients with WPW syndrome.
本研究的目的是评估断层相位分析在检测预激综合征(WPW)患者附加传导通路(ACP)部位中的作用。对20例WPW综合征患者进行了门控发射计算机断层扫描和平面门控血池闪烁显像,其中14例有δ波,6例无δ波(2例间歇性类型和4例隐匿性类型)。将平面和断层相位图像中的异常初始收缩与经心外膜标测和手术证实的ACP部位进行比较。房室环每侧分为8段,将ACP所在段或其相邻段的初始相位识别为正确诊断。在平面相位分析中,14例患者中有8例(57%)正确识别出异常初始相位,而在断层相位分析中,14例患者中有12例(86%)检测到ACP部位。断层相位分析可为WPW综合征患者提供一种有用的辅助方法。
