| Abstract | 「要旨」外科的に副刺激伝導路の位置を確認したWolff-Parkinson-White (WPW) 症候群の25症例を対象に, 心電図同期心プールシンチグラフィを用いて, 心室の早期収縮異常を解析した. 25症例のうち, 右心型11症例全例で右室の早期収縮異常を認めた, また左心型14症例中10例で左室に早期収縮を認めたが, 他の4例では左右差を検出できなかった. 10症例では手術前後に位相解析を施行したが, 術前に位相の左右差を認めた全例において, 術後収縮様式の変化が起こり, 副刺激伝導路に伴う早期収縮が消失することが示された. これらの結果は, WPW症候群の刺激伝導異常に, 高率に心室の早期収縮異常を伴うことを示す知見である. しかし, 術前検査としての正確な副刺激伝導路の位置推定には限界があった. 位相解析は, 副刺激伝導路の診断に従来にない視点を提供するものであり, 手術前後の評価にも有用な検査法と考えられる. |

| Abstract | [Summary] Twenty-five patients with Wolff-Parkinson-White (WPW) syndrome who underwent surgical division of the accessory conduction pathway (ACP) were studied by gated blood pool studies and phase analyses. All of 11 patients with right cardiac type (R-type) had abnormal initial phase in the right ventricle (RV) , while 10 out of 14 patients with left cardiac type (L-type) had initial phase in the left ventricle (LV) . However, in 4 L-type patients, there were no significant differences in the initiation of both ventricular contractions. In 10 patients who had radionuclide studies before and after surgical division of the ACP, the ventricular contraction patterns were apparently changed and the abnormal wall motions induced by the presence of ACPs disappeared. These observations indicate that the abnormal initial contraction is associated with pre-excitation of WPW syndrome. Sensitivities to identify the side of preexcitation were 100% (11/11) for R-type and 71% (10/14) for L-type. However, regarding the detection of the precise site of ACP, the agreement was 48% (12/25) . Therefore, as a method of preoperative study, it seemed difficult to identify the precise localization of the ACP by phase analysis alone. Phase analysis provided interesting informations and was useful for evaluating patients with WPW syndrome before and after surgery. |
