P Wave Duration/P Wave Voltage Ratio Plays a Promising Role in the Prediction of Atrial Fibrillation: A New Player in the Game

<div>P wave duration/P wave voltage cutoff of 854.5 predicts new-onset AF, with a sensitivity of 83.3% and a specificity of 62.0%. The AUC of P wave duration is 0.561. The AUC of P wave voltage is 0.387. The AUC of P wave duration/P wave voltage ratio is 0.728. AF: atrial fibrillation, AUC: area under the curve, ROC: receiver operating characteristic. Diagonal segments are produced by ties.</div>
