mitral valve prolapse (mvp) is a relatively frequent valvular abnormality. in both children and adults with mvp, an increased incidence of ventricular arrhythmias has been reported. qt dispersion, defined as the difference in duration between the longest qt interval and the shortest one, for a given set of electrocardiographic leads has been proposed as a sign of regional difference in cardiac ...

AIMS To perform a comprehensive evaluation of heart rhythm disorders and the influence of disease/therapy factors in a large systemic lupus erythematosus (SLE) cohort. METHODS AND RESULTS Three hundred and seventeen consecutive patients of an ongoing electronic database protocol were evaluated by resting electrocardiogram and 142 were randomly selected for 24 h Holter monitoring for arrhythmi...

BACKGROUND In adults, impaired myocardial repolarization and increased risk of arrhythmia are known consequences of open heart surgery. Little is known, however, about post-operative consequences of cardiopulmonary bypass surgery in children. The aim of this study was to assess ventricular repolarization and coronary perfusion after bypass surgery for atrial septal defect (ASD) repair in childr...

OBJECTIVE Chronic fluoride poisoning is called fluorosis. The aim of the study was to investigate effects of fluorosis on cardiovascular system in children by measuring QT dispersion (QTd), corrected QT dispersion (QTcd), heart rate variability (HRV) and echocardiography findings. METHODS Thirty-five children with dental fluorosis and 26 children as control group were included in this cross-s...

OBJECTIVE Increased QT interval dispersion (QTd) is an electrocardiographic parameter shown to be associated with malignant ventricular arrhythmias and sudden death, and QT dispersion corrected for heart rate (QTc) has emerged as a potentially important predictor of cardiac death. Increased QTd has been detected to be directly related to thyroid-stimulating hormone (TSH) levels in overt hypothy...

BACKGROUND The association between periatrial adiposity and atrial arrhythmias has been shown in previous studies. However, there are not enough available data on the association between epicardial fat tissue (EFT) thickness and parameters of ventricular repolarization. Thus, we aimed to evaluate the association of EFT thickness with indices of ventricular repolarization by using T-peak to T-en...

  Background   Cardiovascular complications are continuing to be a major cause of morbidity and mortality in diabetes mellitus type I (DMTI). The study aimed to evaluate the rate of changes in ECG parameters in children with DMTI compared with healthy childr...

Background: Breath holding spells (BHS) are paroxysmal events with apnea and postural tone with Electrocardiography (ECG) abnormality and epilepsy status reports. The study aimed to compare the ECG parameters’ in epilepsy and breath-holding children compared with healthy children. Materials and Methods: </st...

results two weeks after transplantation, the mean tpe decreased to 0.052 ± 0.002, which was significant compared to pre-hd (p < 0.001) and post-hd (p = 0.019). the mean tpec was 0.059 ± 0.002, which, just in comparison to pre-hd, was significant (p = 0.005). in addition, the mean tpe/qt decreased to 0.143 ± 0.005, which was significant compared to pre-hd (p = 0.018). the mean qtd was 0.066 ± 0....

Abstract Introduction Background SUDEP is leading cause of mortality in patients with chronic refractory epilepsy. Despite several epidemiological studies, case series , monitored and witnessed the exact mechanism not proposed Objective This work was carried out to assess QT interval prolongation epilepsy whether there’s a difference between temporal non-temporal Patients methods study conducte...
