Abstract
The subject of the invention is a method of detecting a QRS complex in an electrocardiogram (ECG) signal, which can be used in biomedical diagnostics. In the method according to the invention, an ABS_DIFF_SHORT signal generated on an output of an ABS_DIFF_SHORT_MODULE module, which is the difference of the current instantaneous value of the ECG signal provided by an ECG_MODULE measuring module, and the mean value of a SHORT_AVG of the ECG signal calculated for a time interval T_SHORT, are monitored using the COMP comparator. Then, the COMP comparator detects the moment when an ABS_DIFF_SHORT signal reaches a threshold TH value previously determined with a TH_MODULE module, and then, when the ABS_DIFF_SHORT signal reaches the threshold TH value, the countdown of a SEARCHING_WINDOW time window starts with a PULSE_GENERATOR pulse generator which has fixed-length for search for a R wave in the QRS complex of the ECG signal. In the next step, using a PEAK_DETECTOR detection module, the maximum value of the ABS_DIFF_LONG_MODULE module produced at its output is recorded during the SEARCHING_WINDOW time window of the ABS_DIFF_LONG signal, which is the difference of the current instantaneous value of the ECG signal and the average LONG_AVG value of the ECG signal calculated for a segment of a T_LONG time segment while the PEAK_DETECTOR detection module the moment of the detected maximum value of the ABS_DIFF_LONG signal is recorded during the SEARCHING_WINDOW time window. After that, the maximum value of the ABS_DIFF_LONG signal detected by the PEAK_DETECTOR detection module is stored by means of a R_AMPLITUDE_MEMORY memory module, which is considered to be the R-wave amplitude in the QRS complex.
