ECG electrodes are small, conductive pads placed on the skin to measure the heart's electrical activity. They are used in electrocardiograms (ECGs) to monitor heart rhythm and diagnose heart conditions. These electrodes, typically made of Ag/AgCl and often with a conductive gel, reduce electrode polarization and allow for stable baseline readings.
