background anthracyclines are important components of many chemotherapeutic protocols. the present study aimed to evaluate the repolarization changes in electrocardiography (ecg) which may predict drug induced arrhythmia. materials and methods in this cross-sectional study, the recorded ecgs were assessed for qt dispersion (qtd), qt corrected dispersion (qtcd), t peak to tend dispersion (tped),...

ramadan fasting is one of the most important religious duties of muslims, that its effect on the heart has not been determined yet. our objective was to evaluate the effect of ramadan fasting on ventricular repolarization as assessed by qt interval, corrected qt interval, qt dispersion or corrected qt dispersion. sixthy healthy subjects aged 20 to 35 years were dispersion included in this study...

background: myocardial ischemia is one of several causes of prolonged qt dispersion. the aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina. methods: we assessed the effects of full revascularization in patients with chronic stable angin...

background: cardiovascular mortality and morbidity are high in chronic renal failure (crf) patients. increased dispersion of qt intervals is known to predispose to ventricular arrhythmias and sudden cardiac death. this study was conducted to assess the effect of hemodialysis (hd) on corrected qt (qtc) intervals and their dispersions (qtd) in chronic hemodialyzed patients. methods: fifty-eight p...

Background: Cardiovascular mortality and morbidity are high in chronic renal failure (CRF) patients. Increased dispersion of QT intervals is known to predispose to ventricular arrhythmias and sudden cardiac death. This study was conducted to assess the effect of hemodialysis (HD) on corrected QT (QTc) intervals and their dispersions (QTd) in chronic hemodialyzed patients. Methods: Fifty-eight p...

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 ...

INTRODUCTION It was aimed to calculate QT intervals in patients with acromegaly and to reveal its correlation between QT intervals, and growth hormone and insulin like growth factor-1. MATERIAL AND METHODS Forty-one patients with acromegaly were enrolled into the study. Another 41 individuals with similar features, such as comorbid diseases, age and sex constituted the control group. The elec...

The present study aimed to evaluate the repolarization changes in electrocardiography (ECG) which may predict drug induced arrhythmia. Materials and Methods In this cross-sectional study, the recorded ECGs were assessed for QT dispersion (QTd), QT corrected dispersion (QTcd), T peak to Tend dispersion (TPe...
