Efficacy of Antitachycardia Pacing for Electrical Storms in Patients with Implantable D...
https://doi.org/10.1111/jce.14891
Journal of Cardiovascular Electrophysiology; Hayashi H, Shimizu W et. al.

Jan 21st, 2021 - Although anti-tachycardia pacing (ATP) is effective in terminating ventricular tachyarrhythmias in patients with implantable cardioverter defibrillators (ICDs), the efficacy of ATP during an electrical storm (ES) and the positive impact on all-cau...

Learning from tragedy-The Jessica Barnett story: challenges in the diagnosis of long QT...
https://doi.org/10.1515/dx-2020-0113
Diagnosis (Berlin, Germany); Graber ML, Olson APJ et. al.

Jan 20th, 2021 - We describe the case of Jessica Barnett, an adolescent girl whose repeated episodes of syncope and near-syncope were ascribed to a seizure or anxiety disorder. The correct diagnoses (congenital long QT syndrome; arrythmogenic right ventricular car...

Medicine Zhao Y, Feng M et. al.

Jan 20th, 2021 - Long QT syndrome (LQTS) is an inheritable disease characterized by prolonged QT interval on the electrocardiogram. The pathogenesis of LQTS is related to mutations in LQTS-susceptible genes encoding cardiac ion channel proteins or subunits. Here, ...

Potential overdiagnosis of long QT syndrome using exercise stress and QT stand testing ...

Journal of Cardiovascular Electrophysiology REFERENCES; Roston TM, De Souza AM et. al.

Dec 31st, 2020 - Long QT syndrome (LQTS) is a dangerous arrhythmia disorder that often presents in childhood and adolescence. The exercise stress test (EST) and QT-stand test may unmask QT interval prolongation at key heart rate transition points in LQTS, but thei...

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. ...

Genetic Variant Might Contribute to Racial Disparity in COVID-19 Cardiac Mortality
https://www.medscape.com/viewarticle/930642

May 17th, 2020 - NEW YORK (Reuters Health) — A genetic variant that increases the risk of drug-induced long QT syndrome (LQTS) and sudden cardiac death (SCD) could contribute to the higher COVID-19-related mortality seen in African Americans, researchers report. I...

Genomic Experts Throw Cold Water on Most Long QT Genes
https://www.staging.medscape.com/viewarticle/924411

Jan 27th, 2020 - Genomics experts say evidence falls short for more than half the genes published and anointed as causing long QT syndrome (LQTS) and assessed routinely on commercial genetic test panels. Of the 17 genes previously reported in the literature to cau...

Can Video Gaming Trigger Dangerous Arrhythmias?
https://www.medscape.com/viewarticle/918728

Sep 18th, 2019 - A new case series raises the question of whether electronic gaming may cause ventricular arrhythmias and contribute to syncope in children with certain underlying conditions. The authors report on four instances of syncope resulting from ventricul...

Large Quantities of Grapefruit Juice Prolong QT Interval
https://www.medscape.com/viewarticle/913187

May 16th, 2019 - Drinking large quantities of grapefruit juice may prolong the QT interval, especially in women and those who already have long QT syndrome (LQTS), new research suggests. Investigators at Tel Aviv Sourasky Medical Center (TASMC) and Sackler Faculty...
