P-wave dispersion is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different-surface ECG leads. It has been known that increased P-wave duration and P-wave dispersion reflect prolongation of intraatrial and interatrial conduction time and the inhomogeneous propagation of sinus impulses, which are(More)
AIMS Cardiac resynchronization therapy (CRT) improves systolic function in heart failure (HF). However, the effects of CRT on left ventricular (LV) diastolic function are not fully understood. The aim of this study was to determine clinical and echocardiographic correlates of improvement in LV diastolic function after CRT. METHODS AND RESULTS Fifty-four(More)
OBJECTIVES Behçet's disease (BD) is a chronic, multisystemic disorder characterised by recurrent oral aphtous ulcers, genital ulcers and ocular inflammation. Vasculitis and thrombotic events are the most important causes of mortality. Vena cava thrombosis, pulmonary artery aneurysms, Budd-Chiari syndrome, peripheral artery aneurysms, dural sinus thrombosis(More)
OBJECTIVES There are some clinical and echocardiographic parameters to predict paroxysmal atrial fibrillation (PAF), but more sensitive predictors are needed. Tissue Doppler imaging may be a sensitive method for this purpose. METHODS Thirty-four patients with PAF and 31 control subjects were studied. Time intervals from the beginning of P-wave to(More)
OBJECTIVE Dynamic pupillometry (DP) is a simple, non-invasive computerized technique for assessment of pupillary light response which provides data concerning the balance of both branches of the autonomous nervous system (ANS). Heart rate (HR) recovery (HRR) after graded exercise reflects cardiac autonomic activity and predicts cardiovascular events. In(More)
The autonomic nervous system (ANS) and cardiovascular function are intricately and closely related. One of the most frequently used diagnostic and prognostic tools for evaluating cardiovascular function is the exercise stress test. Exercise is associated with increased sympathetic and decreased parasympathetic activity and the period of recovery after(More)
The clinical goals of risk stratification of sudden death are to identify subjects who are at high risk of, and eventually to reduce the incidence of, sudden death. Numerous studies have described risk stratification techniques for serious cardiac events in patients following myocardial infarction. However, relatively little information is available(More)
A 59-year-old man was admitted with unresolved chest pain after coronary artery bypass graft surgery that had been performed 3 years earlier; aorta-obtuse marginalis, and aorta-posterior descending artery with the use of a saphenous vein graft and left anterior descending arteryleft internal mammary artery (LIMA). He reported recurrent angina pectoris and(More)
BACKGROUND Cardiac resynchronization therapy (CRT) improves left ventricular (LV) systolic function in heart failure (HF). However, the effects of CRT on right ventricular (RV) systolic function are not fully understood. OBJECTIVE We aimed to determine echocardiographic correlates of improvement in RV systolic function after CRT. METHODS Fifty-four(More)
OBJECTIVE The aim of this study was to evaluate heart rate variability (HRV) and heart rate recovery (HRR) in otherwise healthy ankylosing spondylitis (AS) patients and control subjects. METHODS A total of 28 patients with AS and 30 volunteers matched for age and sex were enrolled. All subjects underwent HRV analysis, exercise testing (ET), and(More)
