Evaluation of Ventricular Repolarisation Features with Novel Electrocardiographic Parameters in Patients with Severe Periodontitis

Abstract

Introduction:Ventricular arrhythmic predictors in severe periodontitis may be linked with cardiovascular events and the sudden death risk. In this study, we evaluated certain electrocardiographic (ECG) ventricular arrhythmic predictors in patients with severe periodontitis.Methods:ECG parameters of 72 patients diagnosed with severe periodontitis, which are indicative of ventricular arrhythmia, were examined, and these parameters were compared with the control group.Results:Compared to the control group, QT interval (QT) (p=0.014), corrected QT (QTc) (p<0.001), QT dispersion (QTd) (p<0.001), QTdc p<0.001), JT interval (p=0.012), JTc interval (p<0.001), T peak and end interval (Tp-e) (p<0.001), Tp-e/ QT ratio (p<0.001), Tp-e/QTc ratio (p<0.001), Tp-e/JT ratio (p<0.001) and Tp-e/JTc ratio (<0.001) were found to be higher in patients with severe periodontitis.Conclusion:Our study showed that arrhythmic ECG markers were significantly prolonged in patients with severe periodontitis. In future extensive prospective studies, we think that these arrhythmic predictors should be evaluated to predict malignant arrhythmias.
