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)
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)
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)
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)
BACKGROUND Although predictive value of heart rate recovery (HRR) has been tested in large populations, the reproducibility of HRR in treadmill exercise test has not been assessed prospectively. This prospective study examined whether HRR index has test-retest stability in the short term. METHODS A total of 52 healthy volunteers without cardiovascular(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 Valves, stenosis, and occlusion in the coronary sinus (CS) may affect the success of left ventricular (LV) lead implantation in cardiac resynchronization therapy (CRT). We present our experience in percutaneous CS intervention (PCSI) to facilitate LV lead implantation and stabilization. METHODS AND RESULTS Transvenous LV lead implantation was(More)
BACKGROUND Increasing evidence-based indications for the implantation of permanent pacemakers (PMs) and implantable cardioverter defibrillators (ICDs) have led to an increase in the rate of device infections. The aim of the present study was to evaluate infection frequency, clinical characteristics, risk factors, and microbiologic and therapeutic features(More)
BACKGROUND Evaluating patients with symptoms suggestive of acute coronary syndrome (ACS) is a time consuming, expensive and problematic process in the emergency department. This study aimed to evaluate the diagnostic and prognostic value of glycogen phosphorylase isoenzyme-BB (GP-BB) in ACS. METHODS A total of 72 patients (mean age 61.8 ± 11.6 years) with(More)
The aim of this study was to evaluate heart rate variability (HRV) and heart rate recovery (HRR) in otherwise healthy ankylosing spondlitis (AS) patients and control subjects. 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 transthoracic echocardiography.(More)
