Abstract: In this study, the effect of ectopic beats and its editing methods on the Poincare plot based HRV indices SD₁ and SD₂ have been assessed. Ectopic free RR interval time series of length 900, 500 and 300 for 10 healthy subjects were analysed by inserting low, medium and high level artificial ectopic beats. SD₁ was found to be more sensitive to ectopic beats than SD₂. The effect has been found to be the function of amount and level of ectopic beats and RR interval data length. The editing methods are found to be more efficient for long-term data.

Keywords: HRV; heart rate variability; ectopic beats; Poincare plot.
