The standard EKG consists of how many leads?

A standard 12-lead ECG uses twelve leads to view the heart’s electrical activity from different directions. Three standard limb leads and three augmented limb leads provide views in the frontal plane, while six chest leads (V1–V6) give horizontal plane views across the chest. Together, these 12 leads give a comprehensive picture of the heart’s electrical activity from multiple angles. In practice, those twelve leads come from ten physical electrodes: four on the limbs and six on the chest.
