Whether the QT interval displays circadian rhythm after heart rate correction is unresolved and the relationship of QT interval to heart rate variability (HRV) is uncertain.To test the hypothesis that there is a circadian rhythm to QT interval and HR

Objective Ascending aortic aneurysm (AAA) is one of the major causes of ventricular diastolic dysfunction. Diastolic dysfunction can induce ventricular repolarization dispersion. Nevertheless, myocardial repolarization dispersion is not yet to be ful

Introduction Benign paroxysmal positional vertigo (BPPV) is a common diagnosis for dizziness patients admitting to emergency department and for initial diagnosis, cardiac causes of dizziness should be excluded at admittance. Electrocardiography (ECG)

Background Incidence of fragmented (fQRS) and predisposing factors in patients with implantable cardioverter-defibrillator (ICD) have not yet been established. Aim To examine incidence of fQRS, associated factors as well as predictive value in identi

Background Several novel ECG markers are proposed to predict the risk of sudden cardiac death in several clinical conditions in the recent years. However, little is known about the association of pericardial fat or obesity with these markers. Objecti

OBJECTIVES: CMD could be the explanation of angina pectoris with no obstructive CAD and may cause ventricular repolarization changes. We compared T-wave morphology and QTc interval in women with angina pectoris with a control group as well as the ass

Coronary microvascular dysfunction (CMD) causes ischemia and is linked to adverse cardiovascular events. Acute transmural ischemia is associated with QT prolongation, but whether CMD affects repolarization is unknown. The aim of this study was to det

Takotsubo cardiomyopathy (TTC) is characterized by acute and reversible ventricular dysfunction in the absence of significant coronary artery disease, typically triggered by acute emotional or physical stress. In the acute phase of TTC, the electroca

Repolarization duration is highly dependent on heart rate. A major concern when evaluating dispersion of repolarization is the possible influence of heart rate on the magnitude of dispersion. Another consideration relates to a potential relationship

A 57-year-old man without prior history of organic heart disease was admitted with a diagnosis of unstable angina because of chest pain and new electrocardiographic (ECG) changes of global T wave inversion and QT interval prolongation. Left and right
