What is artifact in ECG monitoring?

Artifact in ECG monitoring refers to unwanted interference that appears in the ECG signal. These interferences can arise from a variety of sources, such as electrical interference from devices in the environment, muscle contractions, patient movement, or poor electrode contact with the skin.

When artifacts are present, they can distort the true representation of the heart's electrical activity, leading to misinterpretation of the ECG reading. Identifying and addressing artifacts is critical for accurate diagnostics, as they can mimic or obscure real cardiac events.

Understanding artifacts helps monitor technicians refine their techniques, such as ensuring proper lead placement and minimizing external interferences, ultimately ensuring more reliable ECG readings.
