Remodeling of early-phase repolarization: a mechanism of abnormal impulse conduction in heart failure.
BACKGROUND The early phase of action potential (AP) repolarization is critical to impulse conduction in the heart because it provides current for charging electrically coupled cells. In the present study we tested the impact of heart failure-associated electrical remodeling on AP propagation. METHODS AND RESULTS Subepicardial, midmyocardial, and subendocardial myocytes were enzymatically diss...
متن کاملEarly Repolarization in Athletes
Early repolarization (ER) on ECG was initially described in 1936 and has been considered a benign ECG finding for more than half a century. However, in 2008, a seminal study by Haïssaguerre et al challenged this view by demonstrating an association between ER and an increased risk of idiopathic ventricular fibrillation (VF). To reconcile these apparently contradictory views, as well as to bette...

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 کاملEarly Repolarization and Arrhythmia Death
We appreciate the acknowledgement that the foreign gas rebreathing method is highly accurate for measuring the effective cardiac output (the blood flow to ventilated lung). This technique and its development are reviewed in great detail in an outstanding paper by Laszlo (5). Investigators at our institution, UT Southwestern, developed the most common modification of this technique, which made i...
