Despite the FDA’s warning, azithromycin obviously continues to have an important role in treating certain infections (especially pertussis) in the pediatric population. [uspharmacist.com]

Even though the clinical diagnosis of J-LN is rather straightforward, it is important to genotype all these patients because it has been shown by Schwartz et al. [ 3 ] that the smaller group with KCNE1 mutations has a markedly less severe clinical course [ojrd.biomedcentral.com]

LQTS8 Also known as Timothy syndrome (TS), patients show severe QT prolongation on their ECGs, which is combined with syndactyly, baldness at birth, and small teeth in 100% of cases and less penetrant cardiac structural malformations, mental retardation [frontiersin.org]

Subsequent descriptions of an almost identical condition aside from normal hearing were made in 1963 by Romano (2) and 1964 by Ward (3), who described multiple individuals from two distinct families affected by recurrent ventricular fibrillation, a condition [rarediseases.org]

Both of these agents, in this investigation, were given by infusion to sixteen patients with congenitally prolonged QT intervals and9 healthy controls. [aaaai.org]

Complications Most of the time, prolonged QT intervals in people with long QT syndrome never cause problems. However, physical or emotional stress might "trip up" a heart that is sensitive to prolonged QT intervals. [mayoclinic.org]

Without a standardized screening program for LQTS in the U.S., pharmacists might be expected to presuppose that any given patient could be the estimated one in 2,500 who is predisposed to a prolonged QT interval. [uspharmacist.com]

However, the diagnosis of LQTS can be challenging since around 2.5% of the healthy population have prolonged QT-interval while some of LQTS patients do not exhibit abnormal ECG findings. [asperbio.com]

Overview People with LQTS have prolonged QT intervals on their ECGs. The QT interval represents repolarization, or "recharge," of a cardiac cell. [verywell.com]
