PT103448B - NEW MODEL OF TEMPORARY REPRESENTATION OF THE SIGN OF AN ELECTROCARDIOGRAM TRACING 6 GENERALIZED GAUSSIANS - Google Patents

Abstract

The method described is inserted in the field of biomedicine, in particular the medical instrument for the diagnosis of pathologies of the cardiac by electrocardiogram analysis. CONSISTS OF THE AUTOMATIC IDENTIFICATION OF THE HEART PERIODS (SEGMENTATION PHASE) AND, IN EACH PERIOD, IN THE DESCRIPTION OF THE VARIOUS COMPLEXES OF POLARIZATION AND DESPOLARIZATION OF THE MUSCLE MEMBRANES OF THE HEART, CLIMBING 6 (SIX) GENERALIZED GAUSSIANS. EACH COMPLEX IS DESCRIBED BY A GENERALIZED GAUSSIAN THAT IS DEFINED BY 4 (FOUR) CONSTANTS: TEMPORARY LOCATION (AVERAGE), AMPLITUDE, INCLINATION AND OPENING (STANDARD DEVIATION ON A SIMPLE CAUSSIAN). THIS IDENTIFICATION CONSTITUTES A MODEL OF HEART BEHAVIOR AND ALLOWS TO CONSIDERLY REDUCE THE DIMENSION OF THE PHENOMENA REPRESENTATION SPACE, VERY IMPORTANT STEP IN THE OPTIMIZATION OF THE AUTOMATIC CLINICAL IDENTIFICATION SYSTEM (ALGORITHMY) BY RECOGNITION OF PATTERNS AND THAT ALLOWS AN EXTREMELY HIGH COMPRESSION OF THE TEMPORARY SIGNAL. THE METHOD ALLOWS A SIGNAL FILTERING BY RECONSTRUCTION, FACILITATING THE CLINICAL OBSERVATION.

It is important to note that in the present case, it is not possible to determine whether or not the drug is to be used in the treatment of the disease. The electrocardiogram associated with the electrocardiogram, the electrocardiogram of the body is relevant, but it must be known and referenced as the wavelength of the cardiac arrhythmia. This is the puncture of this procedure, the method or the procedure the other part of the sealed seals of the sewage system of Po ver evi a .1; which can be used in such cases which only have a difference in the direction of rotation of the piston rods in the direction of rotation of the piston rods. cut off from the boiling point) and from differences in the yield curve. ,

Each potential difference constitutes a channel, so it is possible to refer to channels rather than potential differences. * In this case it is possible to identify systems of cardiographic recording of 1 to 12 channels. The method described here is applied in each channel, being therefore i campar donated. core cgraiguei; of the disciples. heart risae

The identification platform is used as a cut-off template, the samples being extracted in the intercostal described by this window in each occurrence of the R complex. 4 For each set of samples corresponding to a cardiac recording period, the temporal adaptation of these samples is performed by the identification platform function described in equation (1), R temporal adaptation uses as a criterion of minimization the error of the total hip. The total analytic function in (a) does not have a linear regression to the linear analysis of the data, This method is based on the determination of the final solution.
