  • Method of EKG signal processing and apparatus for performing the method
    Patent number: 9949655
    Abstract: A method of measuring and analyzing the ultra high frequency EKG is performed by measuring the EKG within the frequency range above 250 Hz with a dynamic range of at least 100 dB. In the UHF EKG signal positions of Rm of R wave in QRS complex of EKG are detected on the time axis and the EKG signal is converted to amplitude or power envelopes, the amplitude or power envelopes frequency range is anywhere within the limits from 0.2 Hz to at least 500 Hz. From these envelopes the amplitude and time numerical parameters that describe the myocardium depolarization inhomogeneity and electric myocardium dyssynchrony are determined, and these parameters are used for selecting the patients for multi-chamber stimulators implementation and optimization of their setting.
