Abstract

Abstract: This study explored the value of combined detection of left atrial diameter (LAD) and P-wave dispersion (Pd) in predicting paroxysmal atrial fibrillation in patients with essential hypertension. 69 patients with essential hypertension with paroxysmal atrial fibrillation (observation group) and 207 patients with essential hypertension (control group) were selected in the study. Both of the two groups were performed by biochemical teests, echocardiography and ECG, and the differences of clinical data, Pd and LAD and so on between the two groups were compared. In observation group the comparison of B-type natriuretic peptide (BNP), C-reactive protein (CRP), maximum duration of P wave (Pmax), Pd, LAD, left ventricular mass index (LVMI) was significantly higher than those of the control group (P<0.05). Logistic regression analysis showed that Pd and LAD were the influencing factors of essential hypertension with paroxysmal atrial fibrillation (P<0.05). The ROC curve area of LAD combined with Pd in predicting essential hypertension with paroxysmal atrial fibrillation was 0.919, which was significantly higher than 0.815 and 0.745 predicted by LAD and Pd alone (P<0.05). LAD and Pd are the influencing factors of paroxysmal atrial fibrillation in patients with essential hypertension, the combination of LAD and Pd could have good application value in predicting paroxysmal atrial fibrillation.

Key words: left atrial diameter, P-wave dispersion, essential hypertension, paroxysmal atrial fibrillation, predictive value
