Hypothesis
The purpose of this work was to develop a real-time method and algorithm for suppressing both tremor and power-line interference in ECG.
Conclusion
The proposed method effectively suppresses tremor and power-line interference in ECG recordings without distorting the signal.
Supporting Evidence
- The method preserves useful high frequency components in the ECG signal.
- The recovery error is about 50 μV, which is below the level that may provoke wrong diagnostics.
- The interference is totally eliminated, and tremor is suppressed approximately 25 times.
Takeaway
This study created a way to clean up heart signal recordings by removing unwanted noise caused by muscle movements and electrical interference.
Methodology
The method involves moving averaging, a linearly-angular recovery procedure, and a Savitzky-Golay smoothing filter.
Limitations
The individual shape of the restored waves is not currently considered in the method.
