In Utero Onset of Long Qt Syndrome with Atrioventricular Block and Spontaneous or Lidocaine-Induced Ventricular Tachycardia: Compound Effects of Herg Pore Region Mutation and Scn5a N-Terminus Variant

, 2011
BACKGROUND Mexiletine may protect patients with long QT syndrome (LQTS) type 3 from arrhythmias. However, we found an unusual in utero presentation of intermittent atrioventricutar block and ventricular tachycardia ( spontaneous or lidocaine-induced) in ...

Characterisation of sleep apneas and respiratory circuitry in mice lacking CDKL5

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary CDKL5 deficiency disorder is a rare genetic disease caused by mutations in the CDKL5 gene. Central apneas during wakefulness have been reported in patients with CDKL5 deficiency disorder. Studies on CDKL5‐knockout mice, a CDKL5 deficiency disorder model, reported sleep apneas, but it is still unclear whether these events are central (central ...

Congenital familial long QT syndrome – diagnostic problems

, 2009
Congenital long QT syndrome (LQTS) is characterized by prolongation of the QT interval and T wave abnormalities on electrocardiogram (ECG). The prolongation of QT interval (manifestation of prolongation of ventricular repolarization) predisposes to ...

QT Interval Evaluation in Right Ventricular Pacing: Validation of a Novel Formula

Pacing and Clinical Electrophysiology, EarlyView.
Abstract Background QT interval measurement in the presence of right ventricular pacing (RVP) represents a clinical challenge. We therefore aimed to derive and validate a formula for QT estimation during RVP in a large cohort of pacemaker patients. Methods and Results We prospectively enrolled 100 patients in a derivation cohort and 487 in a validation

Long QT syndrome: A therapeutic challenge

Annals of Pediatric Cardiology, 2008
Congenital long QT syndrome (LQTS) is one of the most common cardiac channelopathies and is characterized by prolonged ventricular repolarization and life-threatening arrhythmias. The mortality is high among untreated patients.

Long QT syndrome in patients over 40 years of age: increased risk for LQTS-related cardiac events in patients with coronary disease.

, 2008
Previous studies of long QT syndrome (LQTS) have focused primarily on the clinical course of affected patients up to 40 years of age to avoid the confounding influence of acquired heart disease on LQTS-related cardiac events in this genetic disorder ...

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

Pacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Misdiagnosis of Long QT Syndrome as Epilepsy at First Presentation

, 2009
Study objective Long QT syndrome has significant mortality, which is reduced with appropriate management. It is known that long QT syndrome masquerades as other conditions, including seizure disorders.
