ECG 60Hz Noise Demo Data

Demo File: ECG 60 Hz Noise.zip

This short file contains an ECG channel affected by 60Hz noise, which is typically caused by electrical interference. 60Hz power is common in the United States and a few other countries. In much of the rest of the world, electrical interference is characterized by 50 Hz noise. Both frequencies are filtered in the same manner.

Use the 60Hz Notch filter in BioLab or analysis to minimize/remove the interference:

R Peak & Artifact Settings
HRV/IMP Analysis Application – Setup Screen – R Peak & Artifact Settings
BioLab Configuration Screen
BioLab Configuration Screen

Once the notch filter is applied, the noise should be significantly reduced.
