<P>PROBLEM TO BE SOLVED: To identify patients indicative of a high probability of the occurrence of ventricle arrhythmia among Brugada syndrome patients by quantizing abnormal elements of an ST segment. <P>SOLUTION: An electrocardiologic device for assisted diagnosis, preferably for the diagnosis of Brugada syndrome or Early Repolarization syndrome. This device allows to characterize the ventricular repolarization wave of an ECG signal collected from a patient. Extracting out of the ECG signal, for each heart beat, an ST segment is constituted of a succession of samples of the ventricular repolarization wave, taken within a time window ([Qon+80 ms, Qon+140 ms]) of a predetermined duration spreading from a moment of window onset defined by a time offset applied to a predetermined temporal origin given by the moment (Qon) of appearance of the QRS complex, whose time position is determined on the ECG signal for each heart beat. For quantization, an elevation index is computed compared to a predetermined reference level (BL), and the persistence and/or variation of this elevation index is analyzed over a succession of heart beats. <P>COPYRIGHT: (C)2009,JPO&INPIT |
