BACKGROUND Short-QT syndrome is an inherited disorder characterized by a short QT interval and an increased risk of sudden cardiac death. The clinical significance of a short QT interval observed in a randomly recorded ECG is not known. Therefore, we assessed the prevalence and prognostic significance of a short QT interval in a general population. METHODS AND RESULTS QT intervals were measur...

torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged qt interval. ecg is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. we describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. most likely, our patients had long qt syndrome ...

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...

one of the important complications of diabetes mellitus that physicians pay less attention to is diabetic autonomic neuropathy(DNA) ,especially cardiac autonomic neuropathy (CAN).this has a poor prognosis and is accompanied by sudden death risk,recently several investigations that were carried out for CAN detection ,suggested that QT-interval prolongation in these patients is an important diagn...

The potassium voltage-gated channel KCNH2 is a well-known gene in which mutations induce familial QT interval prolongation. KCNH2 is suggested to be a risk gene for schizophrenia. Additionally, the disturbance of autonomic control, which affects the QT interval, is known in schizophrenia. Therefore, we speculate that schizophrenic patients have characteristic features in terms of the QT interva...

Background: To the best of our knowledge, there are studies related to QT and QTc interval in patients with hypocalcemia, but no evaluating T wave peak end (Tp-e interval), Tp-e/QT Tp-e/QTc ratios used evaluate cardiac arrhythmia risk ventricular repolarization changes rates. Objectives: Therefore, we aimed investigate whether is a change Tp-e interval, hypocalcemia. Methods: Retrospectively, 2...
