The aim of the present study was to evaluate the QT interval in patients with renovascular hypertension (RV), before and after endovascular revascularization (balloon renal-artery angioplasty with or ...
Background:Epidemiological data suggest increased risk of sudden death during and immediately after hemodialysis. Microvolt T-wave alternans (mTWA) is an electrocardiogram (ECG) measure of abnormal ...
Ventricular repolarization (VR) is a crucial step in cardiac electrical activity because it corresponds to a recovery period setting the stage for the next heart contraction. Small perturbations of ...
The QT interval is the time from the beginning of the QRS complex (ventricular depolarization) to the end of the T wave (ventricular repolarization). The normal QT interval is controversial and ...
We evaluated the incidence of early repolarization among 1395 controls who were representative of the general population and 15 patients classified as having idiopathic ventricular fibrillation, ...
