我们发现，健康受试者心搏间期的连续递增显示出比例不变的、长范围的反相关关系(多达10(4)次心跳)。此外，我们发现心跳间隔增量的直方图可以很好地用Levy稳定分布来描述。对于一组患有严重心脏病的受试者，我们发现分布没有变化，但长期相关性消失了。因此，健康和疾病中不同的比例行为必须与心跳的潜在动态有关。
We find that the successive increments in the cardiac beat-to-beat intervals of healthy subjects display scale-invariant, long-range anticorrelations (up to 10(4) heart beats). Furthermore, we find that the histogram for the heartbeat intervals increments is well described by a Levy stable distribution. For a group of subjects with severe heart disease, we find that the distribution is unchanged, but the long-range correlations vanish. Therefore, the different scaling behavior in health and disease must relate to the underlying dynamics of the heartbeat.
