Scott Hardens Sound Card ECG uses an AD8232 breakout board sending the ECG signal through the microphone jack of a computer sound card. Custom software (free and open source, written in C#) graphs the signal in real time and displays heart rate over time. Scott Hardens Sound Card ECG uses a computer sound card, which has 16 bit, which is research grade. But Scott s software is for Windows PC. Is there software for Matlab, Python, etc.?
Questions to Scott on his youtube channel:
Peter Gamma
«Scott, Is it possible to integrate your free and open source custom software which is written in C#, which graphs the signal in real time and displays heart rate over time in Matlab or Python?”
Scott Harden
«Check the link in the description to my one opamp ECG circuit video. That project makes a similar graph using Python software and you may find that useful»

Peter Gamma
“I know that it is possible to integrate C# into Matlab code. But where is for instance the heart in your software, is it somehow labeled or documented?”
Scott Harden
“The C# code is very simple, available and documented in GitHub, and should be easy to translate into any language (like Matlab) that can graph audio from the sound card. That link is in the description”
