Key result
An algorithm applying discrete wavelet transforms accurately detected premature ventricular contractions and removed noise and leakage effects from the RR signal.
An algorithm using discrete wavelet transforms can accurately detect and correct ectopic beats in Holter monitoring data, improving the reliability of heart rate variability analysis.

May aid ectopic correction in Holter HRV analysis; leaves open prospective validation before clinical use.
D. Barry Keenan (2008) studied Premature ventricular contractions. Discrete wavelet transform algorithm vs. Linear interpolation vs wavelet hard thresholding was evaluated on Detection of PVCs and removal of noise and leakage effects. An algorithm applying discrete wavelet transforms accurately detected premature ventricular contractions and removed noise and leakage effects from the RR signal.
