Fourier analysis was applied to the time activity curve in each pixel, and the phase and amplitude of the basic frequency were computed. From the pixel-by-pixel values, the mean phase of each ventricle was calculated. It was found that the difference between mean phase of right and left ventricle (Ψ(R-L)] was significantly greater in Cp (−13.8°±7.8°) than in Nm (−0.3°±3.9°). This difference was almost twice as great in Cp with RV failure (+15.9°±7.8°) than in those without it (+8.8°±5.1°). Abnormally increased Ψ(R-L) values were detected in about 70% of patients with Cp. Interventricular phase difference had a weak positive correlation with the amplutide of S wave in lead I of the ECG (r = 0.533). It is concluded that in most patients with Cp the phase of the RV contraction is delayed and that this delay may be connected with deterioration of RV performance.
