Build DIY ECG Monitor with Digilent Analog Discovery Studio and NI LabVIEW

Electrocardiography is the process of producing an electrocardiogram (ECG or EKG). It is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat).

With Digilent Analog Discovery Studio and NI LabVIEW, you can build a DIY ECG monitor. The Analog Discovery Studio, available in Elfa Distrelec ,is equipped with 13 instruments, including an Oscilloscope, Logic Analyzer, Spectrum Analyzer, Waveform Generator, and more. It is also compatible to with NI LabVIEW

You can use the Analog Discovery Studio’s Oscilloscope to measure the ECG signal. As the measured signal is of very low amplitude, it first needs to be amplified with external circuitry, which can be built on the Breadboard Canvas and supplied from the Analog Discovery Studio Power Supplies. The received data are sent to LabVIEW, where the postprocessing is done.
