This study compared the phase images of 12 normal subjects and 14 patients with right ventricular and 5 patients with left ventricular preexcitation. The phase images obtained from equilibrium radionuclide ventriculographies in the left anterior oblique portion with an ECG trigger: Fourier analysis was used to measure the phase and amplitude of the variations. In normal subjects the mean difference in phase was nearly zero: in 12 of the 14 patients with right ventricular preexcitation, right ventricular preceded left ventricular contraction (LV phase - RV phase = + 23 degrees); injection of Ajmaline normalised the ECG and suppressed the premature right ventricular contraction during right ventricular preexcitation (LV phase - RV phase = nearly zero), demonstrating a direct relationship between the abnormal depolarisation and abnormal contraction. In left sided Kent bundles, phase imaging did not seem to show significant premature ventricular contraction under basal conditions. Atrial pacing, which accentuated both left and right electrical preexcitation, increased the difference in ventricular phase. Finally, a satisfactory correlation was observed between the presumed locations of the accessory pathways and the zones of premature right and left ventricular contraction.
本研究比较了12名正常受试者、14名右心室预激患者和5名左心室预激患者的相位图像。通过心电触发在左前斜位从平衡放射性核素心室造影获得相位图像：采用傅里叶分析来测量变化的相位和幅度。在正常受试者中，相位的平均差异几乎为零；在14名右心室预激患者中的12名中，右心室先于左心室收缩（左心室相位 - 右心室相位 = +23度）；注射阿马林使心电图正常化并抑制了右心室预激期间的右心室过早收缩（左心室相位 - 右心室相位 = 几乎为零），证明了异常去极化与异常收缩之间的直接关系。在左侧肯特束中，在基础条件下相位成像似乎未显示明显的心室过早收缩。心房起搏加重了左右两侧的电预激，增加了心室相位差异。最后，在旁路假定位置与左右心室过早收缩区域之间观察到了良好的相关性。
