现象和报告异步两个特点。在功率谱中，幂律关系具有自相似性。另一种具有周期性，有明显的功率峰值。然而，在以往的研究中，频谱分析是在SE波形恒定的前提下进行的。在本报告中，我们假设异步位移具有时间结构。通过DFA和功率谱的时间演化分析，我们在功率谱的时间序列中发现了新的结构。在起搏刺激间隔方面具有相当的自相似性和高（约1/f0.9•' 0.2）波动。另一个则持续了几分钟，
phenomenon and reported two features of asynchronous. In power spectrum, one has self-similarity of power-law relationship. The other has periodicity with significant power peak. However, in such previous researche, the spectrum analysis is applied under a premise that the SE waveform is constant. In this report, we assumed that the asynchronous displacement has temporal structure. As a result of the DFA and the analyzing time evolution of power spectrum, we discovered new structures in its time-series. One has fairly self-similarity and high (about 1/f0.9•`0.2) fluctuation with regard to interval of pacing stimuli. The other has longstanding, for several minutes,
