Figure 3. Loss of correlation between the effect of emotion on autonomic balance and on repolarization during hypnotic relaxation. The effect of emotional stress tasks on the LF/HF ratio and ventricular repolarization when the same emotional tasks were performed in the same subjects as in Figure 2 but during hypnotic relaxation. The range of autonomic changes is similar to those in Figure 2, but the effect of emotion on repolarization is markedly reduced during hypnosis, and the correlation is lost for all three measures of repolarization (A, B, and C as in Figure 2).
