BME2210: ECG Lab

Arduino-based ECG amplifier built during the lab

Prof. Albrecht

WPI, B-term & C-term (Cat. I)

In this lab, we will use about $30 in parts to build a working electrocardiograph (ECG) to measure heart electrical signals. In the process, we will learn about electrical circuits, passive components like resistors and capacitors, active components like operational amplifiers (op-amps). Combining these components together, we will learn about common circuit elements like voltage dividers, voltage buffers, and high- and low-pass filters.

An example ECG trace from this circuit displays the P-wave, QRS-complex, and T-wave features. Read here about how these features correlate with the cardiac cycle.
