摘要: Analysis of P-wave duration from the ECG has been widely used to predict onset atrial fibrillation (AF). Given low amplitude Pwaves, this index mainly computed by using signal-averaging algorithms, thus discarding clinically relevant information its time course. This work presents an alternative based on a nonlinear approach, central tendency measure, quantify evolution over time.
