Abstract
Objective To investigate the predictive value of electrocardiogram morphology-voltage-P-wave duration(MVP)score in hypertension complicated by atrial fibrillation(AF).Methods A total of 198 hospitalized patients with hypertension were enrolled,and divided into an AF group(n=99)and a hypertension-only group(n=99)based on the presence of paroxysmal AF.Indicators such as left atrial diameter(LAD),left ventricular end-diastolic diameter(LVEDD),LVEF,P-wave duration,P-wave voltage in lead Ⅰ,MVP score,PtfV1,RV5,and RV5+SV1 were compared between the two groups.The predictive efficacy of MVP score was analyzed using ROC curve analysis.Results The LAD in the AF group was significantly larger than that in the hypertension-only group(P<0.001),while there were no statistically significant differences in LVEDD or LVEF between the two groups(both P>0.05).P-wave duration,positive rate of PtfV1,RV5,RV5+SV1,and MVP score were all significantly higher in the AF group,whereas the P-wave voltage in lead Ⅰ was significantly lower compared with the hypertension-only group(P<0.05).The area under the ROC curve for an MVP score≥4 points in predicting AF was 0.818,with a sensitivity of 0.838 and a specificity of 0.798.Conclusion The MVP score is an independent predictor of AF in patients with hypertension.关键词
