What is an ECG artifact?
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 are motion artifacts TV?
Display motion blur, also called HDTV blur and LCD motion blur, refers to several visual artifacts (anomalies or unintended effects affecting still or moving images) that are frequently found on modern consumer high-definition television sets and flat panel displays for computers.
What can ECG detect?
An ECG can help detect:
- arrhythmias – where the heart beats too slowly, too quickly, or irregularly.
- coronary heart disease – where the heart’s blood supply is blocked or interrupted by a build-up of fatty substances.
- heart attacks – where the supply of blood to the heart is suddenly blocked.

- Pain that Spreads to the Arm.
- You Feel Dizzy or Lightheaded.
- Throat or Jaw Pain.
- You Get Exhausted Easily.
How can you reduce artifacts?
Reducing Motion Artifacts
- Minimize the degree of motion. a. The importance of simple instruction/education of the patient to hold still while the scanner is making noise should not be underestimated.
- Suppress signal from moving tissues. a.
- Adjust imaging sequences and parameters. a.
- Detect and compensate for motion.
What are 3 reasons a person would get an EKG?

- To look for the cause of chest pain.
- To evaluate problems which may be heart-related, such as severe tiredness, shortness of breath, dizziness, or fainting.
- To identify irregular heartbeats.
What causes artifacts in 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 can ECG artifacts be prevented?
Equipment: Adust monitor ﬁlter settings to reduce artifact. Electrodes: Check for electrode gel dry out. Interference: Move ECG cable away from other equipment such as an infusion pump. Cabling: Replace ECG cable and/or leadwires.
