Fourier analysis of radionuclide ventriculography is adept at qualitatively demonstrating interventricular conduction delay in bundle branch block. In this study of eighteen patients, there is a considerable individual variation when the phase delay is expressed as an absolute conduction delay (milliseconds). Much of this variability persists after curve representation by the Fourier function has been optimized. It is suggested that this variability is due to differences in the shape of the right and left ventricular time-activity curves, reflecting differences in contraction and relaxation in the two ventricles. Such differences may be more pronounced in some subjects than others. These results suggest that absolute conduction delay cannot be reliably achieved by this method.
放射性核素心室造影的傅里叶分析擅长定性显示束支传导阻滞时的心室间传导延迟。在这项对18名患者的研究中，当将相位延迟表示为绝对传导延迟（毫秒）时，存在相当大的个体差异。在通过傅里叶函数进行曲线表示优化后，这种变异性仍大部分存在。提示这种变异性是由于右心室和左心室时间-活性曲线形状的差异，反映了两个心室收缩和舒张的差异。这种差异在一些受试者中可能比其他受试者更明显。这些结果表明，通过这种方法不能可靠地获得绝对传导延迟。
