Small sticky patches placed on the torso for ECG are called what?

• A. Leads
• B. Electrodes
• C. Pads
• D. Probes

Answer: (A)

The sticky patches placed on the skin for an ECG are called electrodes. They are the sensing pads that pick up the heart’s electrical activity when placed on the chest and limbs, usually with conductive gel to ensure a good connection. The wires and configurations that connect to these patches are called leads, which provide different views of the heart’s electrical activity on the monitor. So, while the patches themselves are electrodes, the term lead refers to the view or tracing, not the skin patches. Pads and probes aren’t the standard terms for these sensing elements.
