Dominant frequency, atrial fibrillation, electrocardiogramAbstract
This paper presents the behaviour of the dominant frequency of the electrocardiogram (ECG) signal for atrial fibrillation patients before and after preprocessing. The preprocessing method (QRST subtraction) is useful to obtain a clean atrial signal before performing frequency analysis. The QRST subtraction was performed and the dominant frequency before and after QRST subtraction was compared. This study demonstrates a positive result with this technique in comparison with another established technique.
