Fig. 4From: Impact of diastolic dysfunction in patients with preserved ejection fraction undergoing permanent cardiac pacemaker placementReceiver operating characteristic curve (ROC) analysis. The AUC area of 0.721 (95% CI 0.610–0.833; p = 0.004) showed that a pQRSd of 168 ms had a 75.0% sensitivity and a 64.2% specificity for predicting the incidence of composite clinical outcomesBack to article page
