Artifacts are ECG abnormalities that are "a measurement of cardiac potentials on the body surface and are not related to electrical activity of the heart." Consequently, artifacts can distort normal components of the ECG.
- Artifacts are commonly caused by a patient's motion, muscular activity, electromagnetic interference, and electrode malfunction (e.g. misplaced leads).
- It is crucial for physicians to recognize artifacts because they can result in unnecessary testing or treatment.
