“…Thanks to such technology, an acquisition and an automatic processing of normal and long-term ECGs is carried out, a digital coding of the received signals is implemented, and effective methods of filtering and signals analysis, mathematical and electronic modeling, and mapping of electronic potentials are applied [10][11][12][13][14][15]. Because of an increase in the level of automation of ECG study using computer technology, the speed of ECG processing increased with an increase in the completeness and an increase in the convenience of using data with the use of individual storage cards of information for individual use, universal modems, network solutions, etc [16][17][18]. The organization of a large data archive is provided.…”
