Article title

Analysis of atrial electrical activity for atrial fibrillation diagnostics

Abstract (resume)

The algorithm for precise differential diagnostics of atrial fibrillation and atrial flutter was developed. It consists of atrial ECG extraction by means of ICA-method and its spectral analysis. The number of spectral peaks in 2–8 Hz range is calculated. Atrial flutter is refer to one peak and atrial fibrillation is refer to more than one peak. Method was successfully tested with 23 patients with atrial fibrillation or atrial flutter and digital ECGs from Incart ECG-database.
