EFFECT OF ANAESTHESIA ON THE QT INTERVAL [PDF]
A prolonged electrocardiographic QT interval may be harmful during general anaesthesia. It may be prudent, therefore, to select anaesthetic agents which have the least effect on the QT interval. In a controlled study, propofol has been shown to have less effect on the QT interval than thiopentone (P less than 0.05).

Parameters of ventricular repolarization in patients with autoimmune hepatitis
Objective: Autoimmune hepatitis (AIH) is a liver disorder that affects both children and adults. It is characterized by inflammatory liver histology, elevated transaminase level, circulating nonorgan-specific autoantibodies, and increased level of ...

The importance of the epinephrine provocation test for the hidden type-1 congenital long QT syndrome
Congenital long QT syndrome (LQTS) is a genetic channelopathy associated with a high incidence of sudden cardiac death in children and young adults. QT interval prolongation is typically the primary finding on the electrocardiography (ECG) recordings ...

Theory for frequent measurements of spontaneous emissions in non-Markovian environment: beyond Lorentzian spectrum [PDF]
The measurement-result-conditioned evolution of a system (e.g. an atom) with spontaneous emissions of photons is well described by the quantum trajectory (QT) theory. In this work we generalize the associated QT theory from infinitely wide bandwidth Markovian environment to the case of finite bandwidth non-Markovian environment.

Screening for QT Prolongation in the Emergency Department: Is There a Better “Rule of Thumb?” [PDF]
Introduction: Identification of QT prolongation in the emergency department (ED) is critical for appropriate monitoring, disposition, and treatment of patients at risk for torsades de pointes (TdP).

QT-RR HYSTERESIS IS CAUSED BY DIFFERENTIAL AUTONOMIC STATES DURING EXERCISE AND RECOVERY [PDF]
QT-RR hysteresis is characterized by longer QT intervals at a given RR interval while heart rates are increasing during exercise and shorter QT intervals at the same RR interval while heart rates are decreasing during recovery.

A NOS1AP gene variant is associated with a paradoxical increase of the QT-interval shortening effect of digoxin [PDF]
Digoxin is characterized by a small therapeutic window and a QT-interval shortening effect. Moreover, it has been shown that the genetic variants of the nitric oxide synthase-1 adaptor protein (NOS1AP) gene are associated with QT-interval prolongation ...

Effects of atypical antipsychotic drugs on QT interval in patients with mental disorders.
Background Drug-induced QT prolongation is associated with higher risk of cardiac arrhythmias and cardiovascular mortality. We investigated the effects of atypical antipsychotic drugs on QT interval in children and adults with mental disorders ...

Magnetocardiography on an isolated animal heart with a room-temperature optically pumped magnetometer [PDF]
Optically pumped magnetometers are becoming a promising alternative to cryogenically-cooled superconducting magnetometers for detecting and imaging biomagnetic fields. Magnetic field detection is a completely non-invasive method, which allows one to study the function of excitable human organs with a sensor placed outside the human body.

Accurate measurement and assessment of the QT interval [PDF]
QT measurement should be included as part of the systematic interpretation of the electrocardiogram (ECG). Accurate measurement and interpretation of the QT interval will help to identify potentially fatal long QT syndrome (LQTS).
