ABSTRACT Congenital heart disease (CHD) and dermatologic conditions such as lymphedema and acquired melanocytic nevi (AMN) are common in Turner Syndrome (TS). We hypothesized that abnormalities of cranial neural crest cell derivatives drive the skin and heart manifestations of TS. We conducted joint cardiac and skin examinations of volunteers at a 2023

CLINICAL SIGNIFICANCE OF DRUGINDUCED INTERVALS QT AND QTC PROLONGATION
Interval QT prolongation is a predictor of the life-threatening cardiac arrhythmias — polymorphic ventricular tachycardia (torsade de pointes). Long QT syndrome may be congenital or acquired.

Outcome by Sex in Patients With Long QT Syndrome With an Implantable Cardioverter Defibrillator
Background Sex differences in outcome have been reported in patients with congenital long QT syndrome. We aimed to report on the incidence of time‐dependent life‐threatening events in male and female patients with long QT syndrome with an implantable ...

ABSTRACT The Nav1.5 channel, a major isoform of voltage‐gated sodium ion channel, is mainly found in ventricular cardiomyocytes, playing a key role in generating essential cardiac action potentials for normal heart rhythms. Mutations in Nav1.5 have been associated with severe heart conditions such as long QT syndrome, Brugada syndrome, cardiac ...

Acquired long QT syndrome: as risky as congenital long QT syndrome? [PDF]
This editorial refers to ‘Role of implantable cardioverter defibrillator therapy in patients with acquired long QT syndrome: A long-term follow-up’ by G. Monnig et al ., on page 396 Long QT syndrome (LQTS) describes a group of disorders characterized by QT interval prolongation secondary to delayed cardiac repolarization that may either be genetic ...

Prenatal exome sequencing significantly improves diagnostic yield over chromosomal microarray analysis for fetal CNS abnormalities, with a diagnostic yield of 16% in our cohort and 27% in the meta‐analysis. Diagnostic yields vary across different phenotypes. Abstract Introduction Fetal central nervous system (CNS) abnormalities have diverse etiologies,

Smartphone heart monitors in pediatric CIEDs: A pilot study. Smartphone heart monitors did not induce EMI in children with CIEDs, enabling reliable heart rate measurement and accurate identification of ventricular non‐captures. ABSTRACT Background Portable heart monitors enable on‐demand electrocardiogram (ECG) recordings and enhance symptom‐rhythm ...

Timothy syndrome (TS) is a rare genetic disorder characterized by an abnormally prolonged cardiac “repolarization” time (long QT interval). This predisposes individuals to arrhythmias, cardiac arrest and sudden death.

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

Congenital Long-QT Syndromes [PDF]
The congenital long-QT syndromes (LQTS) were initially described approximately 50 years ago.1–3 The principal events are syncope, seizures, and ventricular tachycardia, characteristically torsade de pointes. Most often, this arrhythmia is self terminating, producing a syncopal episode; however, LQTS is responsible for a significant proportion of sudden
