What are the skin-contact devices placed on the chest to record the ECG called?

Explanation:
Electrodes are the skin-contact devices placed on the chest to record the ECG. They are conductive pads that detect the heart’s electrical activity with each beat and send those signals to the ECG machine. The wires and configurations that collect and present those signals are called leads, which provide different views of the heart’s activity, but the pads themselves are the electrodes. Other terms like probes or sensors are too generic for this specific use in ECG. In practice, chest electrodes include the precordial leads V1 through V6 that sit on the chest to capture the heart’s electrical signals.
