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:BaselineDrift.png|Baseline drift. The amplifier in the ECG machine has to re-find the 'mean'.

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 [[Atrial_Fibrillation|atrial fibrillation]]. | Image:electric_noise_ecg.png|Electrical interference from a nearby electrical appliance.
