Abstract. Approaches to optimization of computational algorithms of electrocardiographic signals processing based on extreme correlation method are discussed. An algorithm allowing for tenfold decrease of computation time at retained signal processing quality indicators is proposed, the algorithm is reported to meet the requirements of high-resolution electrocardiography.
