This paper proposes a performant method for R-wave detection. It is based on the analysis of ECG by the multiscale product (MP) using continuous wavelets with one and two vanishing moments. Adaptive thresholding and maxima detection allowed the localization of the QRS. The method can be applied for heart rate monitoring or being a part of a fetal ECG extraction process. Tests on real signals including abdominal ECG from pregnant women have shown that the proposed method can be effective with a preference to the one vanishing moment wavelet namely the first derivative of the Gaussian.
