https://www.ncbi.nlm.nih.gov/pubmed/33941567
Annals of Clinical and Laboratory Science; Zha K, Ye Q

May 4th, 2021 - Long QT syndrome is a cardiovascular disease with a prolonged QT interval. We report a 22-year-old woman presenting with frequent syncopal episodes two months after childbirth. Electrocardiography showed a sinus rhythm, QT interval prolongation, a...

Dose response to nadolol in congenital Long QT Syndrome.
https://doi.org/10.1016/j.hrthm.2021.04.021
Heart Rhythm; Anys S, Arnaud M et. al.

Apr 27th, 2021 - Betablocker therapy is the corner stone to treat long QT syndrome patients (LQTS). Few details are given on the dose to be used. As the response is variable between patients, we systematically evaluated effect of treatment by performing an exercis...

https://doi.org/10.1097/CRD.0000000000000384
Cardiology in Review; Belanger MJ, Kelly EM et. al.

Mar 24th, 2021 - Genetic testing for cardiovascular (CV) disease has had a profound impact on the diagnosis and evaluation of monogenic causes of CV disease, such as hypertrophic and familial cardiomyopathies, long QT syndrome, and familial hypercholesterolemia (F...

Long QT syndrome type 2: mechanism-based therapies.
https://doi.org/10.2217/fca-2020-0234
Future Cardiology; Cox KO, Wang BX

Mar 19th, 2021 - Long QT syndrome type 2 is a life-threatening disorder of cardiac electrophysiology. It can lead to sudden cardiac death as a result of QT prolongation and can remain undetected until it presents clinically in the form of life-threatening cardiac ...

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...
