OBJECTIVE The interlead variation in duration of the Q-T interval on the surface electrocardiogram (Q-T interval dispersion [QTd]) has been shown to predict mortality in type 2 diabetic patients. We evaluated the prevalence of QTd prolongation in the EURODIAB population and its relation to corrected Q-T interval (QTc), sex, age, duration of diabetes, blood glucose control, and complications. RE...
OBJECTIVES This study sought to investigate whether prolongation of the heart rate-corrected QT (QTc) interval is a risk factor for sudden cardiac death in the general population. BACKGROUND In developed countries, sudden cardiac death is a major cause of cardiovascular mortality. Prolongation of the QTc interval has been associated with ventricular arrhythmias, but in most population-based s...
BACKGROUND Increased aerobic capacity can reduce the incidence of cardiovascular disease and the mortality rate. On the other hand, a prolonged heart rate corrected-QT (QTc) interval is associated with an increased risk of arrhythmias, cardiac sudden death and coronary artery disease. AIMS The association of the aerobic capacity and coronary risk factors with QTc interval was investigated in ...
We read with great interest the article by Bestas et al1 entitled “The effect of adrenaline on desflurane-induced prolonged QTc interval: a randomized double-blind trial”, which is published in the current issue of European Review for Medical and Pharmacological Sciences. The Authors1 investigated the effect of adrenaline on desflurane-induced prolonged corrected QT (QTc) interval. They mention...
AIM Prospective survey of the effects of cisapride on QTc interval in neonates given cisapride. METHODS QTc interval was determined just before and 2.9 (0.9) days after outset of the treatment in 49 neonates treated with cisapride between 1 August 1995 and 29 February 1996. RESULTS Cisapride significantly increased QTc interval (p = 0.0001), and this was higher when birthweight or gestation...
Heart Rate-Corrected QT Interval Helps Predict Mortality after Intentional Organophosphate Poisoning
INTRODUCTION In this study, we investigated the outcomes for patients with intentional organophosphate poisoning. Previous reports indicate that in contrast to normal heart rate-corrected QT intervals (QTc), QTc prolongation might be indicative of a poor prognosis for patients exposed to organophosphates. METHODS We analyzed the records of 118 patients who were referred to Chang Gung Memorial...
Sudden death is a leading cause of mortality in sickle cell disease, implicating ventricular tachyarrhythmias. Prolonged QTc on an electrocardiogram (ECG), commonly seen with myocardial ischemia, is a known risk for polymorphic ventricular tachycardia (VT). We hypothesized that prolonged QTc is associated with mortality in sickle cell disease. ECG were analyzed from a cohort of 224 sickle patie...
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is independently associated with QT prolongation among patients with diabetes. It has not yet been determined whether this association remains valid in the general population. We designed an observational study to explore this association. METHODS AND RESULTS We conducted a cross-sectional analysis of 31 116 consecutive participants in our h...
BACKGROUND Methadone is a synthetic opioid, used in treatment of chronic pains. The current study was carried out to evaluate the QTc interval in Iranian causalities (Janbazan) of Iran-Iraq war receiving maintenance methadone treatment. MATERIALS AND METHODS In 2010, one hundred war causalities in Isfahan who chronically take daily dose of 20 mg or more of methadone (more than 2 weeks), and d...
