ECG telemetry circuit diagram - schematic

amplified by the LM4250 operational amplifier connected to a voltage-controlled oscillator NE566 to modulate the oscillator output is used to drive a small speaker, so you can hear the ECG signal. If you want to telemetry, you can use the microphone to pick up the sound output. To put this circuit and the patient connected, you can use the standard viscosity monitor electrodes can also be used a rubber band to tie small metal pieces on the patient's wrist. Each pulse will cause the pitch frequency changes.
