Brief description of the compression of clinical physiological, in particular active, in particular for a holter recording of electrocardiogram or electrograms

摘要

This process is characterized by the following successive steps: a) acquisition (1) of the data by the collection of an electrical signal and sampling of this signal at a given frequency; c) determination (4) of the first derivative (d ') of the sampled signal (d); e) determination (9) of the second derivative (d) of the sampled signal; f) predictive analysis of the sampled signal as a function of a plurality of values of the future of the first and second derivatives and selection (10), for the current sample, of a coding mode among a plurality of encoding modes (11, 12, 13) of predefined switchable dynamically, so as to optimize the overall volume of the codes for the coding of said plurality of values of the future; etg) the compression of data elements for implementing the method of coding (11, 12,13) chosen in step (f).
