PURPOSE The aim of this study was to examine interictal, pre-ictal and ictal autonomic system disturbance by comparing heart rate variability in children with uncontrolled epilepsy with that seen in healthy controls and children with controlled epilepsy. METHODS Our study group included 20 children with refractory epilepsy, our control groups were composed of 20 children with well-controlled ...
Prolongation of the QT interval is associated with torsades de pointes (TdP), especially in children or young adults with long QT syndromes. Susceptibility to TdP arises from increased transmural dispersion of repolarization (TDR) across the myocardial wall. Several anesthetic drugs prolong the QT interval, but their effect on TDR is unknown. TDR can be measured on the electrocardiograph (ECG) ...
INTRODUCTION Regardless of other known factors, left ventricular hypertrophy is considered to be a significant factor which correlates with the risk of cardiovascular complications. In practice, it is very important to predict the outcome for every patient at the beginning of the treatment. OBJECTIVE The aim of the study was to follow the predictive value of non-invasive parameters obtained a...
The impact of chronic hemodialysis on QT dispersion corrected QTdispersion and maximum QT-dispersion
Introduction: Sudden cardiac death is common in patients on hemodialysis and may occur in the immediate postdialysis period when ventricular premature complexes are common. QT dispersion reflecting hetovogelity in ventricle repolarization has been used for predicting patients with risk of malignant arrhythmia and sudden death. The purpose of the study was to assess the effect of hemodialysis on...
The link between increased QT dispersion and cardiac death in subjects with diabetes and arterial disease is well recognised. Corrected QT dispersion was studied in subjects with end stage renal failure on haemodialysis. Thirty one stable, chronic subjects on haemodialysis had 12-lead electrocardiograms (ECGs) taken before and after a single haemodialysis session. The QT interval was measured m...
OBJECTIVE Energy drinks (EDs) are widely consumed products of the beverage industry and are often chosen by teenagers and young adults. Several adverse cardiovascular events and malignant cardiac arrhythmias following consumption of EDs have been reported in the literature. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may co...
BACKGROUND Acute ST-elevation myocardial infarction (STEMI) is associated with significant arrhythmia and cardiac arrest. QT prolongation can occur in the setting of ischemia or acute STEMI as a risk factor for arrhythmia. The goal of this study was to investigate corrected QT interval (QTc), QT dispersion (QTd), and T-wave peak to end (TPE) times in this patient population and evaluate the eff...
