What Does Artifact Mean on Ecg

Electrocardiographic artifacts are defined as electrocardiographic alterations, not related to cardiac electrical activity. As a result of artifacts, the components of the electrocardiogram (ECG) such as the baseline and waves can be distorted. Motion artifacts are due to shaking with rhythmic movement.

What causes artifact on an ECG?

Causes of electrical artifacts on ECGs are manifold. External artifacts are usually caused by line current, which has a frequency of 50 Hz or 60 Hz. Internal electrical artifacts can be caused by tremors, muscle shivering, hiccups or, as in the present case, medical devices.

How do you get rid of artifacts on ECG?

To remove undesirable artifacts, after creating ECG template, this signal was low pass filtered with cutoff frequency of 50Hz. Since the highest frequency power of the ECG signal is between 0.1 Hz and 45 Hz, cutoff frequency of 50Hz is the best choice.
