1. A method, comprising:

  • filtering a digital replica of an electrocardiogram (ECG) signal with a passband filter with cut-off frequencies of about 10 Hz and 35 Hz, the filtering the digital replica including generating a corresponding passband signal;

    filtering out a direct current component from said digital replica of the ECG signal, the filtering out the direct current component including generating a corresponding alternating current (AC) signal; and

    detecting occurrence of peaks of R waves of the ECG signal by;

    processing the passband signal with a finite impulse response filter having a pulse response that is linearly increasing, the processing including generating an intermediate signal; and

    detecting peaks of R waves at zero-crossings between two consecutive maxima of said intermediate signal.
