DETERMINING ONSETS AND OFFSETS OF CARDIAC DEPOLARIZATION AND REPOLARIZATION WAVES |
摘要 |
An exemplary computer-implemented method is disclosed for detection of onset of depolarization on far-field electrograms (EGMs) or electrocardiogram (ECG)- or ECG-like signals. The method includes determining a baseline rhythm using a plurality of body-surface electrodes. The baseline rhythm includes an atrial marker and a ventricular marker. A pre-specified window is defined as being between the atrial marker and the ventricular marker. A low pass filter is applied to a signal within the window. A rectified slope of the signal within the window is determined. A determination is made as to whether a time point (t1) is present such that the rectified slope exceeds 10% of a maximum value of the rectified slope. A point of onset of a depolarization complex in the signal is determined. The point of onset occurs at a largest curvature in the signal within the window. |
