<p>A method and a system for detecting pacing pulses in electrocardiogram (ECG) signals are presented. The method, and system are able to detect pacing pulses even when the ECG waveforms have low signal-to-electromyographic-noise (EMG) ratios. The system can be, in an exemplary embodiment, a part of a generic electrocardiograph. Shortly, in a first step, in order to prevent pacing pulse widening and thus their superimposition to physiological ECG components, the anolog ECG signal of a patient having a pacemaker is digitalised employing a high sampling rate,- thus, in a second step, the method detects the pacing pulses by means of a non-linear filtering (potentially after a linear filtering step) whose output is compared with a threshold.</p> |
