A computational analysis of the effect of sevoflurane in a human ventricular cell model...
https://doi.org/10.1016/j.ejphar.2020.173378
European Journal of Pharmacology; Kojima A, Fukushima Y et. al.

Jul 27th, 2020 - The slowly and rapidly activating delayed rectifier K+ channels (IKs and IKr, respectively) contribute to the repolarization of ventricular action potential in human heart and thereby determine QT interval on an electrocardiogram. Loss-of-function...

Sex-specific IKAS activation in rabbit ventricles with drug-induced QT prolongation.
https://doi.org/10.1016/j.hrthm.2020.07.020
Heart Rhythm; Wu AZ, Chen M et. al.

Jul 24th, 2020 - Female sex is a known risk factor for drug-induced long QT syndrome (diLQTS). We recently demonstrated a sex difference in apamin-sensitive small-conductance Ca2+-activated K+ current (IKAS) activation during β-adrenergic stimulation. The purpose ...

Evaluation of the QT Interval in Patients with Drug-induced QT Prolongation and Torsade...
https://doi.org/10.1111/jce.14687
Journal of Cardiovascular Electrophysiology; Krisai P, Vlachos K et. al.

Jul 23rd, 2020 - Data on the optimal location of the ECG leads for the diagnosis of drug-induced long QT syndrome (diLQTS) with Torsades de Pointes (TdP) are lacking. We systematically reviewed the literature for ECGs of patients with diLQTS and subsequent TdP. We...

Optimal Location of the QT Interval Evaluation in Patients with Drug-induced QT Prolong...
https://doi.org/10.1111/jce.14682
Journal of Cardiovascular Electrophysiology; Lakkis B, Refaat MM

Jul 22nd, 2020 - Long QT syndrome (LQTS) is characterized by prolongation of the QT interval on the electrocardiogram (ECG). Clinically, LQTS is associated with the development of Torsades de Pointes (TdP), a well-defined polymorphic ventricular tachycardia and th...

Potential therapeutic effects of electrogram-guided cardioneuroablation in long QT synd...
https://doi.org/10.1007/s10840-020-00831-w
Journal of Interventional Cardiac Electrophysiology : an International Journal of Arrhythmias and Pacing; Aksu T, Guler TE et. al.

Jul 22nd, 2020 - A significant shortening of the corrected QT interval (QTc) in addition to parasympathetic denervation after cardioneuroablation (CNA) was recently demonstrated in patients with vagally mediated bradyarrhythmias and normal QTc range. This study as...

Determination and Interpretation of the QT Interval
https://www.ahajournals.org/doi/10.1161/CIRCULATIONAHA.118.033943
Circulation Vink,A.,et al

Nov 18th, 2018 - Long QT syndrome (LQTS) is associated with potentially fatal arrhythmias. Treatment is very effective, but its diagnosis may be challenging. Importantly, different methods are used to assess the QT interval, which makes its recognition difficult. ...

Long QT Detection by Watch; Novel Cardiac Devices; Time vs RVU
https://www.medpagetoday.com/cardiology/prevention/72862

May 13th, 2018 - Artificial intelligence can identify congenital Long QT Syndrome on a single lead ECG, even in patients with a normal electrocardiogram, said researchers from AliveCor -- whose KardiaBand add-on for the Apple Watch is such a device -- at the Heart...
