METHOD noise suppression in electrocardiosignals

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly to cardiology, and can be used for automated electric cardiac signal noise cancellation. The method is implemented by the following procedures An electric cardiac signal (ECS) is recorded, split into frequency components; energy density surfaces (EDS) of the ECS frequency components are built up and analysed. While analysing the EDS of the ECS frequency components, low-energy local areas are selected and deleted. Recovering the ECS requires summation of the ECS frequency components derived after the low-energy local areas are deleted. For the purpose of the EDS analysis control, a noise level is measured in the recovered signal, and the control responses are formed for the change of selection threshold shift of the low-energy areas.;EFFECT: method enables the effective electric cardiac signal noise cancellation.;1 tbl, 12 dwg
