Arduino ECG & Heart Health Analysis

A beginner step to get started with AD8232 for ECG readings and perform processing and analysis in python

Steps to follow

• Configure the arduino with AD8232 module. Here's a good website to help out setup https://www.how2electronics.com/ecg-monitoring-with-ad8232-ecg-sensor-arduino/
• Use the ecg.ino as the code to be compiled and uploaded into arduino controller, change the PIN number accordingly.
• Attach the sensor pads to your body, again follow the website above for placement area.
• Run ecg_plot_save.py. python ecg_plot_save.py to generate csv file of readings. Currently if both plot and saving enabled the iteration on my computer only up to 50 per second (it/s) while it able to go 120 it/s if plot self.is_plot = False . 120 it/s is expected since the delay configured in arduino.ino is 8ms
• Just wait a couple of minutes and close the program. By default the program save into ecg_records.csv
• Open ECG & HRV.ipynb Notebook and run all cells to get HRV information and produce a filtered ECG readings
• Open DeepLearning Classification of atrial fibrillation.ipynb to get the ECG classification for Atrial Fibrillation (AF)
