Tachograms of interbeat intervals obtained from ECGs are usually down sampled before heart rate variability analysis is undertaken. Various resampling frequencies ranging from 1Hz to 8Hz have been reported in the literature, with 4Hz being optimal for frequency domain analysis. This paper reports on the outcome of applying different resampling frequencies for Poincaré Plot-derived feature analysis. Significant differences were noted between 1Hz, 2Hz and 4Hz resampling of 300 RR interval time series. From a clinical perspective, the optimal resampling frequency for discriminating between type 2 diabetics and nondiabetics using Poincaré analysis was 1Hz. Therefore the frequency chosen for resampling needs to take into consideration the HRV algorithm applied, the length of the time series, and the pathophysiology entity being investigated.
