Cardiocerebral channelopathy caused by KCND3 mutation in a child: A case report

Frontiers in Pediatrics, 2022
Early repolarization syndrome is rare in children. Mutation of genes encoding ion channels could display mixed electrophysiological phenotype of Kv4.3 including both cardiac phenotype (early repolarization syndrome, atrial fibrillation) and cerebral ...

Younger People Show More Changes in Repolarization with Exercise

, 2012
Purpose: Cardiac repolarization is a complex phenomenon that depends on heart rate (HR), autonomic nervous system (ANS) activity, age, gender and diseases/pathological conditions etc.

High heart rate associated early repolarization causes J‐waves in both zebra finch and mouse

Physiological Reports, 2021
High heart rates are a feature of small endothermic—or warm‐blooded—mammals and birds. In small mammals, the QT interval is short, and local ventricular recordings reveal early repolarization that coincides with the J‐wave on the ECG, a positive ...

Early Repolarization in Athletes [PDF]

Circulation: Arrhythmia and Electrophysiology, 2016
Early repolarization (ER) on ECG was initially described in 1936 and has been considered a benign ECG finding for more than half a century.1,2 However, in 2008, a seminal study by Haissaguerre et al3 challenged this view by demonstrating an association between ER and an increased risk of idiopathic ventricular fibrillation (VF).

Diclofenac Prolongs Repolarization in Ventricular Muscle with Impaired Repolarization Reserve [PDF]

, 2012
Background: The aim of the present work was to characterize the electrophysiological effects of the non-steroidal anti- inflammatory drug diclofenac and to study the possible proarrhythmic potency of the drug in ventricular muscle.

Diabetes mellitus attenuates the repolarization reserve in mammalian heart [PDF]

, 2007
Objective: In diabetes mellitus several cardiac electrophysiological parameters are known to be affected. In rodent experimental diabetes models changes in these parameters were reported, but no such data are available in other mammalian species ...

Early Repolarization in the Athlete

Journal of the American College of Cardiology, 2009
An “abnormal” resting electrocardiogram is common in top-ranking, endurance-trained athletes ([1][1]). These abnormalities belong to physiological changes induced by training, as sinus bradycardia, high QRS and T-wave voltages, and early repolarization (ER), consisting of an elevation of QRS–

Electrocardiographic Changes in Mitral Valve Prolapse Syndrome [PDF]

Journal of Cardiovascular and Thoracic Research, 2014
Background- Mitral valve prolapse syndrome (MVP) is most common valvular abnormality in young and is correlated with increased frequency of cardiac dysrhythmias and sudden death. The aim of this study was to compare frequency of "early repolarization" in

Long-Term Follow-Up of Subjects Without Overt Heart Disease With an Early Repolarization/J Wave Electrocardiographic Pattern

Frontiers in Cardiovascular Medicine, 2022
AimsThe “early repolarization” (ER) pattern and J wave are frequent findings on standard ECG. Controversial data have recently been reported about their prognostic implications in healthy subjects, but no longitudinal prospective study specifically ...

An extreme example of early repolarization

The Anatolian Journal of Cardiology, 2018
Once accepted as a benign phenomenon, electrocardiographic early repolarization pattern is now considered to have significant clinical importance. Haissaguerre et al. (1) were first to describe the possible association between early repolarization pattern and idiopathic ventricular fibrillation. Since then, numerous studies have documented the clinical
