OBJECTIVES The study was designed to comprehensively evaluate the circadian effects of aldosterone blockade on autonomic tone and QT dispersion in chronic heart failure (CHF). BACKGROUND Spironolactone therapy given in addition to angiotensin-converting enzyme inhibitors improved survival in CHF, but the mechanism of its benefit is uncertain. Experimental evidence suggests that aldosterone ma...

AIMS Arrhythmogenic right ventricular dysplasia is a rarely diagnosed cardiomyopathy, but a frequent cause of ventricular arrhythmia and sudden cardiac death. QT interval dispersion, measured as an interlead variability of QT, is a marker of dispersion of ventricular repolarization and, hence, of electrical instability. The present study was conducted to assess the occurrence of QT dispersion a...

OBJECTIVE Familial mediterranean fever (FMF) is the most common auto-inflammatory disease that is characterized by recurrent, self-limited attacks of fever and serous membrane inflammation. Patients with inflammatory rheumatic diseases are considered to have a raised cardiovascular diseases risk. The aim of this study was to investigate; by means of P wave dispersion (Pd) and QT dispersion (QTd...

One of the timeliest and most prescient books I’ve come across in the last fifteen years is Edward Chancellor’s popular history of financial speculation Devil take the Hindmost. Chancellor had worked as an investment banker for Lazard Brothers in London and had contributed to the Financial Times and The Economist and so was well acquainted with what he called “This Bubble World” (3), echoing th...

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...

OBJECTIVE The aim of this study is to examine depression and anxiety related arrhytmia risk in fibromyalgia syndrome (FMS). METHODS Fifty-nine patients with the diagnosis of FMS and 20 control participants were included in the study. Fibromyalgia Impact Questionnaire (FIQ), Visual Pain Scale (VPS) surveys were applied to determine the severity of the disease. Beck Anxiety (BAS) and Beck Depre...

OBJECTIVE Coronary slow flow (CSF) phenomenon is described by angiographically normal coronary arteries with delayed opacification of the distal vasculature. Several studies have suggested that the interval from the peak to the end of the electrocardiographic T wave (Tp-Te) may correspond to the transmural dispersion of the repolarization and that increased Tp-Te interval and Tp-Te/QT ratio are...

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...

OBJECTIVE Glycemic variability (GV) is a new term with the episodes of hyper and hypoglycemia in diabetic patients. Both prolonged QT interval and QTd are potential risk factors for malignant ventricular arrhythmias affecting the mortality of different groups of patients including diabetes mellitus. In this study, we aimed to evaluate if the glucose variability increasing the QTc interval and Q...

Lily Winter " Islam's borders are bloody, and so are its innards. " (Huntington 1996: 258) " The insistence, if only implicitly, on a choice-less singularity of human identity not only diminishes us all, it also makes the world much more flammable. " (Sen 5) " If you want to know whether Islam, democracy, modernity and women's rights can coexist, go to Indonesia. " (Hillary Clinton, qtd. in Kur...
