Image:Noise_move.png | Image:Noise_move.png| Movement artifacts | ||
Image:ECG_Parkinson.png | Image:ECG_Parkinson.png| Increasing movement artifacts in a Parkinson patient. The patient was in sinus rhythm! (which doesn't show on this short recording) | ||
Image:BaselineDrift.png | Image:BaselineDrift.png| 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. | ||
Image:cardioversion_from_afib.jpg | Image:cardioversion_from_afib.jpg| Cardioversion from atrial fibrillation to sinus rhythm, with clear baseline drift. | ||
Image:electric_noise_ecg.png | Image:electric_noise_ecg.png| Electrical interference from a nearby electrical appliance. A typical example is a 100 Hz background distortion from fluorescent lights. Not to be confused with arrhythmias#atrial fibrillation|atrial fibrillation. | ||
Image:electric_noise_ecg2.jpg | Image:electric_noise_ecg2.jpg| Another example of an artefact caused by an electrical appliance. The patients rhythm is regular. This strip shows 10 QRS complexes. | ||
