We performed electrophysiological study and radionuclide phase imaging in a patient with intermittent Wolff-Parkinson-White syndrome type A and left bundle branch block. The presence of a left-sided accessory pathway was proven by eccentric retrograde atrial activation. Phase-imaging revealed delayed left ventricular phase angles when left bundle branch block was present in the electrocardiogram. There was an advance of early phase angles at the ventricular insertion of the accessory pathway as well as delayed phase angles in the rest of the left ventricle when the pre-excitation pattern was seen electrocardiographically.
我们对一名患有间歇性A型预激综合征和左束支传导阻滞的患者进行了电生理研究和放射性核素相位成像。通过偏心逆行心房激动证实了左侧旁路的存在。相位成像显示，当心电图出现左束支传导阻滞时，左心室相位角延迟。当心电图出现预激图形时，旁路心室插入处的早期相位角提前，而左心室其余部分的相位角延迟。
