AIM Breath-holding spells are common in infancy and early childhood, and patients are frequently referred to paediatric cardiology clinics for exclusion of heart disease. Recent data reveal subsequent development of epilepsy and neurocardiogenic syncope. Autonomic dysregulation and increased vagal stimulation leading to cardiac arrest and cerebral ischaemia is considered as the cause. Iron defi...

QT dispersion (QTd) is a measure of interlead variations of the surface 12-lead electrocardiogram (ECG). Increased QTd, found in various cardiac diseases, reflects cardiac instability and is associated with increased risk for cardiac death. Research suggests a link between antipsychotics, ECG abnormalities (QT prolongation) and increased sudden cardiac mortality rates. However, QTd analysis has...

Objectives. This study was planned to evaluate the relation between QT dispersion (QTd) and multi-vessel coronary artery disease in acute coronary syndrome. Methods. Two hundreds and twenty-five consecutive patients with a diagnosis of non-ST segment elevation acute coronary syndrome were included. Three groups were defined as a single vessel, two vessels, and three vessels. Echocardiographic, ...

BACKGROUND Electrocardiographic changes are well known to appear with acute cerebrovascular events. OBJECTIVE To investigate if QT dispersion (QTd) is increased in patients who have an acute stroke and if this increase could be related to lesion extent and/or localization. DESIGN The study group consisted of 36 patients who had an acute stroke and no history or signs of cardiovascular disea...

Chronic hepatitis B (CHB) is a chronic inflammatory viral disorder. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-e) may correspond to the transmural dispersion of repolarisation and that increased Tp-e interval and Tp-e/QT ratio are associated with malignant ventricular arrhythmias. Impaired autonomic function has been describe...

background: qt interval parameters have been suggested as a predictor of lethal arrhythmia and mortality in patients with myocardial infarction. the aim of the present study was to compare the value of qt interval indices in patients presenting with non-st-segment elevation myocardial infarction (nstemi) between a group of patients with type 2 diabetes mellitus and a nondiabetic group of patien...

We would like to thank the authors for the letter [1] regarding our manuscript entitled “Prolonged Tp-e interval and Tp-e/QT correlates well with modified Rodnan skin severity score in patients with systemic sclerosis” [2] published in “Cardiology Journal”. We would also like to thank the Editor for the opportunity to respond to this letter. In the study we aimed to evaluate Tp-e interval and T...

OBJECTIVE To evaluate the effects of corrected QT dispersion (QTcd) on patients` prognosis with early stage non-lacunar ischemic stroke, regardless of location of the lesion. METHODS In this non-randomized prospective study, stroke patients were evaluated in the intensive care unit of Cukurova University Hospital, School of Medicine, Adana, Turkey, from 2002-2003. Neurologic symptoms of all s...

OBJECTIVE Breath holding spells (BHS) are common involuntary reflexes in infancy and early childhood. Differential diagnosis should embrace Long QT Syndrome (LQTS) and paroxysmal abnormalities of rhythm. The aim of this study was to compare QT dispersion (QTd) in children with breath holding spells and normal controls. MATERIALS & METHODS QT dispersion and Corrected QT(QTc) dispersion were me...
