Phase analysis of ECG-gated radionuclide ventriculography was performed during sinus rhythm and atrial pacing for 11 patients with the Wolff-Parkinson-White (WPW) syndrome. During sinus rhythm, phase analysis demonstrated abnormal early-emptying segments reflecting preexcitation in six of the 11 patients. In the remaining five patients, the precise site of abnormal early-emptying could not be detected. Atrial pacing increased the degree of pre-excitation, and abnormal early-emptying segments became clear in all patients. Our study demonstrated the utility of atrial pacing in performing phase analysis for patients with the WPW syndrome. Seven patients had abnormal early-emptying segments; four of them with ECG type A, in the left ventricle, and three of them with ECG type B, in the right ventricle. These results were consistent with results of the body surface and electrophysiologic mapping. In patients with posterior septal accessory pathways, phase analysis suggested probable laterality of the accessory pathway.
对11例预激综合征（WPW）患者在窦性心律和心房起搏时进行了心电图门控放射性核素心室造影的相位分析。在窦性心律期间，相位分析显示11例患者中有6例存在反映预激的异常早期排空节段。在其余5例患者中，未检测到异常早期排空的确切部位。心房起搏增加了预激程度，所有患者的异常早期排空节段均变得清晰。我们的研究证明了心房起搏在对WPW综合征患者进行相位分析中的作用。7例患者有异常早期排空节段；其中4例为A型心电图，位于左心室，3例为B型心电图，位于右心室。这些结果与体表和电生理标测结果一致。在有后间隔旁路的患者中，相位分析提示旁路可能的侧别。
