Aims In long QT syndrome (LQTS), primary prevention improves outcome; thus, early
identification is key. The most common LQTS phenotype is a foetal heart rate (FHR)< 3rd …

Objectives and methods Psychotropic drugs may prolong the corrected QT interval (QTc),
which has been associated with torsades de pointes (TdP). Our aim is to measure the …

Drug safety trials require substantial ECG labelling like, in thorough QT studies,
measurements of the QT interval, whose prolongation is a biomarker of proarrhythmic risk …

Introduction The QT interval, a critical parameter in electrocardiography (ECG), is
challenging to analyze accurately because of variations in T-wave morphology, especially in …

Congenital long QT syndrome (LQTS) is an inherited arrhythmia syndrome associated with
sudden cardiac death. Accurate interpretation and classification of genetic variants in LQTS …

Background In patients with congenital long QT syndrome (LQTS), the risk of ventricular
arrhythmia is correlated with the duration of the corrected QT interval and the changes in the …
