Table 2 Comparison of Short-Time Transform Frequency Measurements

From: A new transform for the analysis of complex fractionated atrial electrograms

Type Mean_FT Mean_EA SD_FT SD_EA
Paroxysmal, DF (Hz) 5.18 5.25 0.62 0.61
Persistent, DF (Hz) 6.39 6.35 0.55 0.50
Significance p < 0.001 p < 0.001 NS NS
Combined 5.78 5.82 0.44 0.41
  1. DF = dominant frequency, FT = Fourier transform, EA = ensemble average analysis, SD = standard deviation.
