Artifacts
The gallery of images below shows a variety of EKG artifacts that are due to tremor, movement, movement disorders and electrical interference. These artifacts should not be confused with an abnormality in the patient's electrocardiogram. Atrial fibrillation can be confused with these artifacts.
 Movement artifacts |
 Increasing movement artifacts in a Parkinson patient. |
 Baseline drift. The amplifier in the ECG machine has to re-find the 'mean'. This often occurs right after lead connection and after electric cardioversion. |
 Cardioversion from atrial fibrillation to sinus rhythm, with clear baseline drift. |
 Electrical interference from a nearby electrical appliance. A typical example is a 100 Hz background distortion from fluorescent lights. Not to be confused with atrial fibrillation. |
 Another example of an artifact caused by an electrical appliance. The patients rhythm is regular. This strip shows 10 QRS complexes. |
