Analysis of atrial fibrillation: from electrocardiogram signal processing to clinical management

Philos Trans A Math Phys Eng Sci. 2009 Jan 28;367(1887):235-53. doi: 10.1098/rsta.2008.0162.


The analysis of atrial fibrillation in non-invasive ECG recordings has received considerable attention in recent years, spurring the development of signal processing techniques for more advanced characterization of the atrial waveforms than previously available. The present paper gives an overview of different approaches to the extraction of atrial activity in the ECG and to the characterization of the resulting atrial signal with respect to its spectral properties. So far, the repetition rate of the atrial waves is the most studied parameter and its significance in clinical management is briefly considered, including the identification of pathomechanisms and prediction of therapy efficacy.
