Abstract: This study explored the predictive value of ECG P wave characteristics in patients with essential hypertension complicated with paroxysmal atrial fibrillation. 66 essential hypertension patients with paroxysmal atrial fibrillation were selected (observation group), and 80 patients with unilateral essential hypertension were selected as the control group, ECG parameters were compared between the two groups, the P-wave maximum duration (Pmax), P-wave dispersion (Pd) and P-wave variation (Pv) in the observation group were significantly higher than those in the control group, respectively (P<0.05). The area under the ROC curve of Pmax, Pd and Pv in predicting paroxysmal atrial fibrillation was 0.709, 0.944 and 0.528. Pmax, Pd and Pv in the observation group were significantly lower than those before treatment (P<0.05). The area under the ROC curve of effective predicted by Pd was 0.878 (P<0.05), while the area under the ROC curve of effective predicted by Pmax was 0.621 (P>0.05). The P wave feature has certain application value in predicting the concurrent paroxysmal atrial fibrillation and the curative effect of sacubitril and valsartan.
