DEVICE FOR SELECTING QRS-COMPLEXES OF ELECTRIC CARDIAL SIGNAL Russian patent published in 1994 - IPC

FIELD: medical equipment. SUBSTANCE: device has mating unit 7, which has output connected with input of R-tooth selector 8. Input of unit 7 is connected to input bus. Mating unit has inverter 1. Input of the inverter has to be the first input of mating unit and is connected with the first input of the first analog switch 2. Output of the inverter is connected with the first input of the second analog switch 3. Outputs of the first and the second switches are integrated and connected with input of R-tooth selector. The second input of the first analog switch is connected with inverse output of trigger 6. The second input of the second analog switch is connected to direct output of the trigger. Input of the trigger is connected with output of the third comparator 5 which has the second (reference) input for receiving threshold voltage U_thr. The first input of the third comparator is connected with output of RC-circuit and output of switch 4. EFFECT: widened functional capabilities. 2 cl, 4 dwg
