Electrophysiologic substrate in congenital Long QT syndrome: noninvasive mapping with electrocardiographic imaging (ECGI).
BACKGROUND Congenital Long QT syndrome (LQTS) is an arrhythmogenic disorder that causes syncope and sudden death. Although its genetic basis has become well-understood, the mechanisms whereby mutations translate to arrhythmia susceptibility in the in situ human heart have not been fully defined. We used noninvasive ECG imaging to map the cardiac electrophysiological substrate and examine whethe...
متن کاملCardiac electrophysiological substrate underlying the ECG phenotype and electrogram abnormalities in Brugada syndrome patients.
BACKGROUND Brugada syndrome (BrS) is a highly arrhythmogenic cardiac disorder, associated with an increased incidence of sudden death. Its arrhythmogenic substrate in the intact human heart remains ill-defined. METHODS AND RESULTS Using noninvasive ECG imaging, we studied 25 BrS patients to characterize the electrophysiological substrate and 6 patients with right bundle-branch block for compa...
متن کاملThe relationship between Tonic-Clonic sizures in children and increased time of ventricular repolarization
Background: Long QT syndrome (LQTS) is a disorder in which electrical cardiac ventricular repolarization is impaired. It results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. Long QT Syndrome may present as tonic-clonic seizure or a seizure-like disorder. By taking a superficial electrocardiogram (ECG) and proper diagnosis,...
متن کاملEarly Repolarization Syndrome; Mechanistic Theories and Clinical Correlates
The early repolarization (ER) pattern on the 12-lead electrocardiogram is characterized by J point elevation in the inferior and/or lateral leads. The ER pattern is associated with an increased risk of ventricular arrhythmias and sudden cardiac death (SCD). Based on studies in animal models and genetic studies, it has been proposed that J point elevation in ER is a manifestation of augmented di...
متن کاملComparison of vastus medialis muscle activity in patients with patellofemoral pain syndrome after a period of flexural strength training with and without electrophysiological feedback exercises
Given that more than 50 percent of patellofemoral pain syndrome include of overuse injuries, the aim of this study was to compare the vastus medialis muscle activity in individuals with patellofemoral pain syndrome after a period of strength and flexibility training with and without the electrophysiological feedback. A total of 30 subjects (15 men and 15 women) participated in this study. Subje...
