Abstract：Objective:To investigate the value of P wave dispersion(Pd) in predicting a trial fibrillation in patients with paroxysmal hypertension. Method:A total of 95 cases with hypertensive patients were divided into two groups according to whether the patient had atrial fibrillation.Pmax,Pmin and Pd of patients were detected by synchronous 12 lead ECG,and at the same time left a trial diameter(LAD) and left ventricular ejection fraction(LVEF) were detected by ultrasonic cardiogram.The differences of Pmax,Pmin,Pd,LAD and LVEF between two groups were compared.Result:Pmax,Pd and LAD in the observation group were higher than that in the group(P<0.01,P<0.01,P<0.05),and LVEF in the observation group was higher than that in the group(P<0.05).The specificity and positive predictive value of Pmax>110 ms+Pd≥40 ms were the highest in three indicators,and the sensitivity and negative predictive value of Pmax>110 ms+Pd≥40 were the lowest.Conclusion:Pd is a predictor of hypertension combined with paroxysmal a trial fibrillation,and the predictive value of it combined with Pmax was higher.
