Role of P Wave Duration and Tissue Doppler Imaging as Predictive Indicators for Paroxysmal Atrial Fibrillation in Hypertensive Patients

Background: Atrial fibrillation (AF) is the most prevalent chronic arrhythmia in heart. AF accounts for one-third of rhythm disorder hospitalizations. increases profoundly risk stroke, heart failure, and death. This study used P-wave transthoracic echocardiography with tissue Doppler imaging (TDI) to determine paroxysmal predictors hypertensive individuals.
 Methods: case control was performed on 100 adult patients. They were classified into two equal group: Group I included patients diagnosed have AF. II (control group) normal sinus rhythm. All subjects subjected electrocardiographic conventional Imaging measurements.
 Results: Pmax had significantly increased PAF compared PAL, PAR, PAI, LR, LI IR In Multivariate logistic regression analysis, Pmax, found be independent PAF. Therefore, PAL significant Best cut-off values were: (118, 81, 61, 49.9, 34, 20 16 ms) sensitivity (76, 96, 88, 82, 86 77.5 ), specificity (84, 100, 98, 92, 78, 82 76) AUC (0.850, 0.979, 0.987, 0.961, 0.836, 0.891 0.798) respectively.
 Conclusions: Electrocardiographic analysis echocardiographic TDI may identify hypertension at AF, since combination help predicting development individuals.
