Circulation: Arrhythmia and Electrophysiology, 2019 BACKGROUND Long QT syndrome is a potentially lethal yet highly treatable cardiac channelopathy. Although β-blocker therapy is standard for most patients, concomitant therapy with sodium channel blockers, like mexiletine, is often utilized for patients ...

Sex and Rate Change Differences in QT/RR Hysteresis in Healthy Subjects
Frontiers in Physiology, 2022 While it is now well-understood that the extent of QT interval changes due to underlying heart rate differences (i.e., the QT/RR adaptation) needs to be distinguished from the speed with which the QT interval reacts to heart rate changes (i.e., the so ...

Measurement and interpretation of electrocardiographic QT intervals in murine hearts. [PDF]
, 2014 Alterations in ECG QT intervals correlate with the risk of potentially fatal arrhythmias, for which transgenic murine hearts are becoming increasingly useful experimental models. However, QT intervals are poorly defined in murine ECGs.

Evaluation of differences in automated QT/QTc measurements between Fukuda Denshi and Nihon Koden systems. [PDF]
PLoS ONE, 2014 Automatic measurement becomes a preference, and indeed a necessity, when analyzing 1000 s of ECGs in the setting of either drug-inducing QT prolongation screening or genome-wide association studies of QT interval.

Palbociclib has no clinically relevant effect on the QTc interval in patients with advanced breast cancer. [PDF]
, 2018 The aim of this study was to assess the potential effects of palbociclib in combination with letrozole on QTc. PALOMA-2, a phase 3, randomized, double-blind, placebo-controlled trial, compared palbociclib plus letrozole with placebo plus letrozole in ...
