The circuit is designed for experimental or teaching, and it can be used to hear the ECG signal voltage. ECG signal voltage is amplified by the LM4250 op amp for modulating the NE566, which is connected as voltage-controlled oscillator, and oscillator output is used to drive small speakers, so you can hear the ECG signal. If you want to telemetry, you can use the microphone to pick up the sound output. In order to connect the circuit and the patient, you can use standard adhesive monitoring electrodes, you can also use a small piece of metal to tie to the patient's wrist by rubber.
