Early 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...
متن کاملRole of Early Repolarization Pattern in Increasing Risk of Death.
BACKGROUND An early repolarization pattern (ERP) has been hypothesized to be arrhythmogenic in experimental studies, but the prognostic significance of the ERP in the general population is controversial. We performed a meta-analysis to examine the link between ERP and the risk of sudden cardiac arrest (SCA), cardiac death, and death from any cause. METHODS AND RESULTS We performed a literatur...
متن کاملCardiac potassium channel subtypes: new roles in repolarization and arrhythmia.
About 10 distinct potassium channels in the heart are involved in shaping the action potential. Some of the K+ channels are primarily responsible for early repolarization, whereas others drive late repolarization and still others are open throughout the cardiac cycle. Three main K+ channels drive the late repolarization of the ventricle with some redundancy, and in atria this repolarization res...
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...
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 ...
