Abstract
A flexible ECG monitoring system including pace pulse detection. The monitoring system includes a potable monitor 102 that can be worn by a patient 120 or connected to a docking station 104. The portable monitor 102 includes an A/D converter 210, 208 and a digital signal processor 202. ECG signals are digitized and the digital signal processor derives a signal that is an estimate of the slope of the ECG signal. Pace pulses are detected by processing the slope signal, including use of a threshold that is dynamically updated based on the recent history of the slope signal. Detected pace pulses are removed prior to certain ECG filtering and reinserted following such filtering.
