Background: The algorithm for precise differential diagnostics of atrial fibrillation and atrial flutter was recently developed.
Materials and methods: 19 patients with atrial fibrillation and several digital ECGs from database.
Results: The algorithm developed is based on atrial ECG extraction by the blind source separation method and its spectral analysis. The number of spectral peaks in the 2-9 Hz range is calculated. Atrial flutter refers to one peak while atrial fibrillation refers to more than one peak.
Conclusions: This method was successfully tested in patients with atrial fibrillation or atrial flutter on several digital ECGs from database. The algorithm was 100% reliable.
