FIELD: medicine.SUBSTANCE: invention relates to medicine, in particular to cardiology, and can be used for adaptive suppression of noise in electrocardiosignal. Electrocardiosignal is registered, decomposed into frequency constituents, restored and output. In addition, distinguished are electrocardiosignal cardiocycle and section of isoline on TP segment of electrocardiosignal cardiocycle. Construction of surfaces of energy density of distinguished electrocardiosignal cardiocycle and isoline section is performed on the basis of Hilbert-Huang transform in coordinate system energy-frequency-time. Threshold surface is formed from surface of energy density of isoline section. Surface of energy density of distinguished electrocardiosignal cardiocycle is compared with formed threshold surface.EFFECT: invention will make possible to increase accuracy of electrocardiosignal restoration and reduce level of residual noise in elecrocardiosignal.14 dwg |
