In a standard 12-lead EKG, where is the ground electrode placed?

Explanation:
The ground electrode in a standard ECG serves as a stable reference point to minimize electrical noise and interference, helping the device measure the heart’s electrical activity cleanly. It is placed on the right leg, separate from the limb leads that use the arms and legs to form the heart’s tracing. So the ground is the right leg, not the arms.
