Patent ID: 8260406

Claim:
System for analysis of ECG curvature comprising a computer system, which computer system performs a mathematical analysis, which mathematical analysis comprises at least the following steps: a: the system comprises input means connected to at least one ECG source, b: a number of different parameters are isolated and stored in the computer system, c: the computer system select a first number of parameters from at least one main group, d: the computer system combine the selected parameters in at least a first mathematical analysis, whereby the parameters are selected from groups of symmetry (S1-S72), flatness (F1-F91), duration (D1-D47) and/or complexity (C1-C468), e: extract a segment in of the ECG curvature in the mathematical analysis, f: which segment is corresponding to a interval between defined electrocardiographic points, g: which segment is used as input to a first algorithm, h: where a second fiducial point algorithm automatically calculates fiducial points at the segment, i: where concavity intervals are evaluated on subsegments of the ECG segment and form the basis of up- and downwards concavity quantification, j: where the system based on at least the first and the second algorithm detects and quantifies concavity on ECG curvatures; wherein at least one segment of the ECG repolarization signal is selected, corresponding to the interval between the Twave onset and Twave offset, which segment is normalized so that the amplitude range (y) is equal to a first predefined value in the selected interval.
