DEVICE TO ELIMINATE DRIFT OF ISOELECTRIC LINE OF ELECTRO-CARDIOSIGNAL Russian patent published in 2011 - IPC A61B5/402 

FIELD: measurement equipment.

SUBSTANCE: invention relates to the field of medicine, in particular, to electrocardiography and is a device for elimination of isoelectric line drift. Device comprises a low-pass filter connected to analogue-digital converter, a unit for identification of reference counts, connected to a unit of memorising N counters and a subtraction unit. Besides the device comprises the following components connected to the outlet of the analogue-digital converter - a unit of RR interval duration definition, the first and second memory units. The first memory unit is connected to the unit of reference counts identification and the unit of N counts memorising. The unit of N counts memorising is connected to a unit of compensating signal generation, connected to the subtraction unit and the second memory unit. The second memory unit is connected to the subtraction unit. The unit of RR interval definition with one of its outlets is connected to the first and second memory units, by the second outlet - to the first memory unit, and by the third outlet - to the unit of reference counts identification.

EFFECT: using invention makes it possible to eliminate isoelectric line drift in the whole range of cardiac beats frequency.
