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...

background: prolongation of qt interval is one of the most important abnormalities in cardiovascular system of cirrhotic patients. the aim of this survey was determination of propranolol effect on frequency adjusted qt interval (qtc). materials and methods: thirty six cirrhotic patients (m/f=20/16, mean age:56 â± 3.8 years) and 40 healthy age and sex matched controls (m/f=25/15, mean age: 58 â±...

background: prolonged qt interval may lead to serious arrhythmias and ventricular fibrillation, hence prevention of the qt-interval prolongation is crucial for physicians. the aim of this study was to assess the influence of intravenous lidocaine on the qtc interval resulting from spinal anesthesia with bupivacaine. methods: in a randomized double blind trial, fifty male patients with mean age ...
