Introduction
The AD8232 is a neat little chip used to measure the electrical activity of the heart. This electrical
activity can be charted as an ECG or Electrocardiogram. Electrocardiography is used to help
diagnose various heart conditions. Now for the disclaimer:
NOTE: This device is not intended to diagnose or treat any conditions.
