Abstract
A method for detecting an R-wave from an ECG signal (x(t)) derived from a living body, the method comprising the steps of (a) acquiring the ECG signal from the living body, (b) digitizing the ECG signal into a digital ECG signal (x(t)), (c) filtering the digital ECG signal with a bandpass filter () and applying an absolute value filter () thereto to create a filtered ECG signal (g(t)), (d) for each sequential value of the filtered ECG signal, comparing () the filtered ECG signal to an ECG tracking threshold (TT), (e) if the filtered ECG signal is no greater than TT, incrementing a counter (), but if greater than TT, setting the counter to zero; and (f) comparing () the counter to a predetermined refractory count RC and, if the count is equal to RC, outputting an R-wave trigger indicating that an R-wave has been detected.
