Time statistics of heartbeat intervals and cauchy distribution

By analysing the time series of beat-to-beat ( R-R ) intervals, we found that Cauchy or Bright-Wigner (BW) type distributions give good representations of the real R-R intervals, even in different regimes of ergometric ECG measurements. The separation of healthy subjects from those with stable angina pectoris (SAP) can be seen in the 2-dimensional parameter space of the Cauchy distribution.
