- •
There is a large prevalence of deviations from the recommended cut-offs of ECG filtering.
- •
This study investigates the impact of 40 Hz high pass filtering compared to 150 Hz high pass filtering on ECGs perceived quality and clinical interpretation.
- •
We demonstrated that the 40 Hz high pass filtering does not affect ECG clinical interpretation, while allowing better quality of tracings.
