Abstract:
Background : Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp - e) may correspond to the transmural dispersion of repolarization and that increased Tp - e interval and Tp - e/QT ratio are associated with malignant ventricular arrhythmias.Objectives : The aim of this study was to evaluate ventricular repolarization by using the Tp - e interval and Tp - e/QT ratio in patients with rheumatoid arthritis (RA), and to assess the relation with inflammation.Patients and methods : A case - control study includes Seventy patients (57 females, 13 male mean age 48.3±12.3years) with RA and 46 controls(39 females , 7males ; mean age , 46.8 ±13.1 years) were studied. From the 12 - lead electrocardiogram, Tp - e interval and Tp - e/QT ratio were measured. Blood samples were taken for erythrocyte sedimentation rate (ESR) .These parameters were compared between studied groups. The relationship between ventricular repolarization and inflammation was assessed by Pearson correlation coefficients. Results : Tp - e interval and Tp - e/QT ratio were increased in RA patients compared to the controls (72.47 ±6.6vs 66.17 ±3.4ms, 0.19 ±0.01 vs 0.17±0.01; p<0.001 and p<0.001, respectively). The Tp - e/QT ratio was also correlated with ESR(R=0.3, P=0.02) Conclusion : In RA patients, the increased frequency of ventricular arrhythmias may be explained by increased indexes of ventricular repolarization and their relationship with inflammation
