Background: In previous work, we demonstrated that Root Mean Square (RMS), Dominant Frequency (DF) may differentiate atrial fibrillation (AF) into Paroxysmal (PAF), Persistent (PeAF), and Permanent (PmAF) AF. Here, we further proposes quantized Approximate Entropy (qApEn), quantized Shannon Entropy (qSE) and Mean Frequency (MF) for analysis of fibrillatory wave.
Methods: 224 patients were enrolled: 112 PAF (61.6±12.5 years), 48 PeAF (55.6±13.1 years), 64 PmAF (65.3±9.3 years). Lead II of ECG were analyzed to extract characteristics of f waves; RMS for amplitude (tall vs. short), DF and MF for frequency (fine vs. coarse), qApEn for polymorphism (complex vs. simple), and qSE for randomness.
Result: In pair-wise comparison shown in tables 1 and 2 and figure 1, qApEn showed the most effective diagnostic value for distinguishing PeAF from PmAF (PeAF, 0.103±0.053; PmAF, 0.068±10.3; AUC=0.746; p-value<0.001), qSE for PAF from PmAF (PAF, 2.07±0.33; PmAF, 1.71±0.31; AUC=0.780; p-value<0.001), and DF for PAF from PeAF (PAF, 4.79±2.00; PeAF, 5.98±1.90; AUC=0.658; p-value=0.001).
Conclusions: In our analysis, DF has the most critical values to distinguish PAF and PeAF, qSE between PAF and PmAF, and qApEn between PeAF and PmAF. As AF progresses from PAF into PeAF and PmAF, f waves generally display a decrease in amplitude (RMS), an increase in frequency (MF) and the RR interval, a lesser degree of randomness (qSE). The complexity of f waves (qApEn), however. slightly increases in PeAF but decreases in PmAF.
