Atrial
fibrillation (AF) is a type of arrhythmia that causes the atria to beat
irregularly, which can occur intermittently or persist over time. AF can be
detected by the presence of F-waves in electrocardiogram (ECG) signals, which
can be extracted using QRST cancellation. Principal component analysis (PCA)
can be used to isolate ventricular activity from the ECG signal. To assess AF
beat by beat, one can utilize the F-wave frequency ratio (FWFR), which is the
proportion of the spectral area in the 4-10 Hz frequency range to the overall
spectral area. In this study, the FWFR was used to determine AF episodes, and
the results showed that in Normal (N),
conditions, the FWFR was 45% [43-46%], while in Persistent Atrial
fibrillation (PAF) conditions, it was 53% [52-54%], and in non-Persistent
Atrial fibrillation (nPAF) conditions, it was 45% [39-48%]. The study suggests
that QRST cancellation using PCA and FWFR can be used to quantitatively and
qualitatively estimate AF, as well as differentiate between normal, persistent
AF, and non-persistent AF conditions.
