Key result
Frequency-domain analysis of P waves (AR20 ≥ 1.5) provided an 83% predictive accuracy for detecting paroxysmal atrial fibrillation, with significant differences compared to controls (P<0.01).
Why the study?
Does frequency- and time-domain analysis of P-SAECG accurately detect patients with paroxysmal atrial fibrillation?
Case-Control (n=42)

May support P-wave analysis for paroxysmal AF detection; leaves open prospective validation before clinical adoption.
Hiraki et al. (1998) conducted a case-control in Paroxysmal atrial fibrillation (n=42). Frequency- and time-domain analysis of P-SAECG vs. Controls was evaluated on Predictive accuracy for paroxysmal atrial fibrillation (p=<0.01). Frequency-domain analysis of P waves (AR20 ≥ 1.5) provided an 83% predictive accuracy for detecting paroxysmal atrial fibrillation, with significant differences compared to controls (P<0.01).
