Dispersion of QT and QTc interval in healthy children, and effects of sinus arrhythmia on QT dispersion [PDF]

Heart, 1998
Objective To determine the normal values of QT and QTc dispersion and the effects of sinus arrhythmia on QT dispersion in healthy children. Patients and setting The study was carried out in a university hospital on 372 local schoolchildren (200 male,

Conformable Microelectrode Arrays Integrated with a Scoop‐Shaped Slide‐Well for Dynamic Electrophysiological Profiling of Patient‐Derived Cardiac Organoids

Advanced Science, Volume 13, Issue 31, 4 June 2026.
A flexible, ultrathin multi‐channel microelectrode array (MEA) conformally integrated onto a curved slide‐well enables stable electrical interfacing with 3D cardiac organoids. The geometry‐guided self‐alignment allows simultaneous recording of extracellular field potentials and contractile motion from irregular, beating tissues.

A Remarkable Point: QT Dispersion in Trained Athletes

Haseki Tıp Bülteni, 2010
Aim: It is a common belief that QT dispersion can increase the risk of cardiac death by inducing arrhythmias and that this is a consequence of changes in the ventricular muscles due to heavy training.

Stability of Magnetized Disks and Implications for Planet Formation

, 2010
This paper considers gravitational perturbations in geometrically thin disks with rotation curves dominated by a central object, but with substantial contributions from magnetic pressure and tension.

The Association of QT Dispersion and QT Dispersion Ratio with Extent and Severity of Coronary Artery Disease [PDF]

Annals of Noninvasive Electrocardiology, 2006
Background: Although prolongation of the QT intervals in acute ischemic conditions, such as acute myocardial infarction, intracoronary balloon inflation, and exercise induced ischemia, has been shown, association of rest QT intervals with extent and severity of stable coronary artery disease (CAD) has not been assessed so far.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

QT dispersion in the electrocardiogram in hemodialysis and peritoneal dialysis patients

Saudi Journal of Kidney Diseases and Transplantation, 2014
To evaluate QT dispersion (QTd) in dialysis patients in an analytic cross-sectional study, three groups were enrolled: Hemodialysis (HD), peritoneal dialysis (PD) and control (30 patients in each group) to study QT parameters in 12-lead ...

Molecular Clock on a Neutral Network

, 2007
The number of fixed mutations accumulated in an evolving population often displays a variance that is significantly larger than the mean (the overdispersed molecular clock). By examining a generic evolutionary process on a neutral network of high-fitness

Crystal Facet‐Polysaccharide Matching in CFS‐P Nanocrystals Drives Fungal Uptake, Vacuole Destruction, and Selective Antifungal Activity

Advanced Science, EarlyView.
Facet‐engineered PVP‐capped CuFeSe2 nanocrystals exhibit potent, selective antifungal activity by strongly binding cell‐wall mannan, enabling vacuolar entry and organelle disruption. High‐index facets show superior mannan affinity, validated by theoretical calculations and experiments. CFS‐P induces vacuolar cavitation, mitochondrial abnormalities, and

QT interval and P wave dispersion in slow coronary flow phenomenon

ARYA Atherosclerosis, 2018
BACKGROUND: Slow coronary flow (SCF) phenomenon is an angiographic finding which is defined as slow contrast passage through coronary arteries which may predispose patients to serious cardiac complications such as fatal arrhythmias.
