Evaluation of Tp-e interval and Tp-e/QT ratio in patients with rheumatoid arthritis.

Objectives: 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. 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.

Study Design: Ninety-six patients (72 females, 24 males; mean age 43.
