Which term refers to a diagnostic test that records electrical activity of the heart over time?

Explanation:
Recording the heart's electrical activity over time is done with an electrocardiogram. This diagnostic test uses skin electrodes to pick up the heart’s electrical signals and creates a tracing that shows rhythm and timing of the cardiac cycles, including the P wave, QRS complex, and T wave. It helps detect abnormal heart rhythms, rate issues, and potential conduction problems. The other terms don’t fit: a venipuncturist draws blood, hemiplegia is paralysis on one side of the body, and semicolon is punctuation.
