What does the prefix 'electro-' refer to?

Explanation:
Electro- denotes electricity or electrical activity. In medical terms, this prefix is used whenever the focus is on electrical signals or measurements rather than on a specific body part. For example, electrocardiography records the heart’s electrical activity, and electromyography measures the electrical activity of muscles. This distinguishes the concept from anatomical names like heart, nerve, or muscle themselves, which are identified with cardio-, neuro-, and myo- (or sarco-).
