Background Breath-holding spells (BHS) are brief periods when young children stop breathing for up to 1 minute and are widely recognized types of non-epileptic severe occasions in early stages of childhood. This study aimed to evaluate QTd and QTc changes in children with breath-holding spells compared with healthy children. <stron...

It is known that in patients with ischemic heart disease, QT dispersion (QTd) predicts ventricular arrhythmia and sudden cardiac death and that major coronary risk factors such as smoking, diabetes mellitus, hypertension increase QTd. It is not clear whether, in coronary artery disease, QTd increases because of ischemia or co-existence of coronary risk factors. In this study, we aimed to invest...

Purpose: It is thought that arrhythmias are responsible for sudden deaths in patients with mitral valve prolapse (MVP). QT intervals may predict malignant arrhythmia potential in these patients. The aim of the present study is to assess QT variables in patients with MVP. Methods : We studied 46 patients with non-rheumatic, uncomplicated and isolated MVP and 25 healthy control subjects. All indi...

BACKGROUND AND OBJECTIVES The study aimed to evaluate the correlation between electrocardiographic (ECG) parameters and presence and extent of coronary artery disease (CAD) to indicate the usefulness of these parameters as predictors of severity in patients with stable CAD. SUBJECTS AND METHODS Two hundred fifty patients, without a history of any cardiovascular event were included in the stud...

UNLABELLED Co-morbidity between physical disease, especially cardiovascular, and psychological disturbances is well documented. In psychiatric patients, the potential for dysrhythmogenic incidences is increased by the fact that many psychiatric medications influence cardiovascular function. AIM The aim of the study was to examine the dysrhythmogenic potential of 30 psychiatric patients (group...

Previous studies assessing effect of ischemia on ventricular repolarization are mostly directed toward patients with coronary artery disease (CAD); however, similar reports on cardiac syndrome X (CSX) are scarce. Whether microvascular dysfunction of CSX and ischemia induced by CAD produce comparable effect on ventricular repolarization is unclear and deserve further studies. In the present stud...

Background: Patients with coronary slow flow phenomenon (CSFP) exhibit the following characteristics: Predominantly middle-aged males, majority have mixed pattern angina, persistent chest pain sensations after therapy, and many had repeated invasive non-invasive examinations.&#x0D; Objectives: Our study aimed to determine base of predictors in patients presenting chronic syndrome.&#x0D; Methods...
