Why the study?
Does a detector based on multivariate analysis of frequency components improve discrimination between local and distant electrical activity in unipolar cardiac electrograms compared to single-band filtering?
Does a detector based on multivariate analysis of frequency components improve discrimination between local and distant electrical activity in unipolar cardiac electrograms compared to single-band filtering?
Multivariate analysis of frequency components, particularly including high frequencies (500-1000 Hz), improves the discrimination of local versus distant electrical activity in unipolar cardiac electrograms.
