The invention relates to medicine, namely to medical technology, and can be used in mass screening of the population, as well as for accelerated ECG recording in the clinic.

The purpose of the invention is to reduce the time and simplify the use of an electrocardiograph without attendants.

The drawing shows a schematic diagram of an attachment to an electrocardiograph.

To electrocardiograph 1 (for example, EK1T-04), the prefix 2 is connected by cable 3. The prefix consists of a plastic case (not shown), two electrodes 4 (E | and En) fixed on two buttons 5 (on the schematic diagram of the prefixed buttons Si and $ 2 ), LED 6 (on the HLI concept), which induces switching on the electrocardiograph 1. The left electrode is connected to the yellow cable 7 leads (from the electrode from the patient's left hand), and the right electrode to the red 8 (from the electrode from the patient's right hand). The electrocardiograph has a connector 9 (X 1) for connecting the cable

3 through a plug (not shown).

Consecutively connected buttons 5 are connected with an electrical circuit parallel to the power supply voltage switch of the electrocardiograph (for the EC1T-04 electrocardiograph, switch B2-1). A series-connected LED b and a resistor Yu (Ri), which limits the current through the LED 6, are connected to the ground bus with one lead and the positive lead of the power supply to the other.

The prefix serves to create contact between the patient's fingers and the electrodes.

4 and simultaneous remote switching of the electrocardiograph.

The prefix works as follows.

The connector 9 on the side wall of the electrocardiograph 1 inserts the plug of the cable 3, the wires from the electrodes from the left 7 and right 8 hands (yellow 7 and red 8) into the left and

the right side of the set-top box Lead selector switch is set to 1 standard lead. After preparation, the device is turned off, the Record button (EK1T-04 electrocardiograph) is left on.

To register the ECG, the patient with the thumbs of the left and right hands with the same force presses and holds down the button 5 for 445

s, required to register 5-6 cycles of heart rate.

When the buttons 5 are pressed, the electrical circuit closes, parallel to the power supply voltage switch B2-1. About powering

the electrocardiograph 1 signals the burning of the LED 6. At the same time, the springs of the buttons 5 under compression create sufficient constant contact of the electrodes 3 with the patient's fingers. When closing the electrical

the circuit turns on the electrocardiograph and records 5-6 cycles of heart contractions in 1 standard lead.

In the process of using an STB, ECG recording time is reduced, so

both the imposition of electrodes and the activation of the electrocardiograph are performed simultaneously. The use of an electrocardiograph without maintenance personnel is achieved by the fact that the patient independently performs both the imposition of electrodes and the remote activation of the device.
