Abstract

Behçet's disease (BD), a multisystemic inflammatory disorder, has been associated with a number of cardiovascular dysfunctions, including ventricular arrhythmias and sudden cardiac death. The mechanism of increased ventricular arrhythmias in BD remains uncertain. The aim of the present study was to assess the ventricular repolarization by using the Tp-e interval, Tp-e/QT ratio, and Tp-e/QTc ratio as candidate markers of ventricular arrhythmias in patients with BD. A total of 42 patients (mean age: 42.71±10.99 years) with BD and 50 sex- and age-matched healthy volunteers (mean age: 39.24±11.32 years) as the control group were evaluated. The risk of ventricular arrhythmia was evaluated by calculating the electrocardiographic, the Tp-e interval, and the QT, QTc, Tp e/QT, and Tp-e/QTc ratios. QTmax (p=0.005), QTcmax (p=0.015), QTmin (p=0.011), and QTcmin (p=0.024) were statistically significantly higher in the BD group than in the control group. The Tp-e, cTp-e, Tp-e/QT, and Tp-e/QTc ratios were also significantly higher in patients with BD than in the control group (80.26±4.55 and 74.74±6.47, respectively, p<0.001; 88.23±6.36 and 82.68±7.81, respectively, p<0.001; 0.21±0.01 and 0.20±0.01, respectively, p=0.008; and 0.19±0.01 and 0...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
