Estimates of repolarization dispersion from electrocardiographic measurements.
BACKGROUND Repolarization dispersion (Rd) is frequently mentioned as a predictor of cardiac abnormalities. We present a new measure of Rd based on the root-mean-square (RMS) curve of an ECG lead set and compare its performance with that of the commonly used QT dispersion (QTd) measure with the use of recovery times measured from directly recorded canine electrograms. METHODS AND RESULTS Using...
متن کاملElectrocardiographic Early Repolarization
1520 The early repolarization (ER) pattern (ERP), initially described as elevation of the ST segment of ≥1 leads on the 12-lead ECG, has long been considered a benign phenomenon. However, more recent studies have demonstrated positive, negative, and neutral associations between an ERP and various end points, including all-cause, cardiac, and arrhythmic mortality. These recent studies have used ...
متن کاملElectrocardiographic evidence of ventricular repolarization remodelling during atrial fibrillation.
AIMS Some atrial fibrillation (AF) patients develop excessive QTc prolongation and torsade de pointes when they take QTc-prolonging antiarrhythmic drugs (class IA/III) immediately after termination of AF. We hypothesized that this is caused by changes in ventricular repolarization during AF. We aimed to establish whether such 'ventricular repolarization remodelling' occurs. METHODS AND RESULT...
متن کاملElectrocardiographic quantitation of ventricular repolarization.
Quantification of the electrocardiographic ventricular repolarization involving the T-U wave complex is usually performed with reference to the axis of the T wave and the QT interval duration. A novel quantitative approach to improve the description of ventricular repolarization was applied to the digitized electrocardiograms of 423 normal subjects. Six electrocardiographic repolarization chara...
متن کاملCardiac repolarization: insights from mathematical modeling and electrocardiographic imaging (ECGI).
Cardiac repolarization is a complex rate dependent process. At the cellular level, it depends on a delicate dynamic balance of ion channel currents. At the heart level, it is spatially heterogeneous, leading to spatial gradients of potential and excitability. This article provides insights into the molecular mechanisms of the delayed rectifiers I(Kr) (rapid) and I(Ks) (slow) that underlie effec...
