Patent ID: 8116859

Claim:
A device for an assisted electrocardiologic diagnosis comprising means for characterizing the ventricular repolarization wave of an ECG signal collected from a patient, said ECG signal having been preliminarily sampled and digitized, said device comprising: means for determining the time position of a moment of appearance of the QRS complex on said ECG signal for each heart beat; extracting means for isolating out of the ECG signal, for each heart beat, an ST segment comprising a succession of samples of the ventricular repolarization wave, taken within a time window of a predetermined width, said width having a moment of window onset, said moment of window onset having a time offset from a predetermined temporal origin; wherein said predetermined temporal origin comprises said determined moment of appearance of the QRS complex; quantizing means for computing an elevation index of said ST segment compared to a predetermined reference level; and means for analyzing over a succession of heart beats, selected from the group consisting of the persistence the elevation index and the variation of the elevation index.
