Abstract

The complexity of the heart beat intervals of 7 patients with arrhythmia absoluta and 11 healthy control subjects was investigated using the box dimension D_B and the correlation dimension D _c. Using a 2D embedding space, the box dimension assumed values greater than 1.40 (mean: 1.53±0.010) in all arrhythmic patients whereas in all control subjects D_B was less than 1.31 (mean: 1.13±0.012). D_c was computed in a 10D embedding space. The mean value of D_c was 7.26±1.69 in the arrhythmia group and 5.70±1.51 in the control group. Although this difference of the means is significant with 2.01·10^-12, a separation between arrhythmic and healthy persons was not possible
