• LQTS can arise from mutation of one of several genes.
• LQTS can be inherited in an autosomal dominant or a much less common autosomal recessive fashion.
• With better knowledge of the genetics underlying LQTS, more precise treatments hopefully will become available.
• Current studies say LQTS may occur in 1 of every 10, 000 to 15, 000 births.
• Nadolol is one of the preferred beta-blockers in the management of patients with LQTS for shortening of the QT interval and prevention of ventricular arrhythmia.
• A number of specific gene loci have been identified to be associated with LQTS . Genetic testing for LQTS is clinically available and may help to direct appropriate therapies.

• In 2000 the MMRL research team uncovered evidence linking Sudden Infant Death Syndrome to a congenital heart defect, the Long QT syndrome ( LQTS ) published in The New England Journal of Medicine.
• With LQTS, the heart's electrical system has some type of short circuit that can cause a person to be more susceptible to a very fast heart rhythm known as torsade de pointes.
• In 1856 he provided possibly the first account of long QT syndrome ( LQTS ), of which he described a case where a deaf girl collapsed and died while being publicly scolded at school.
• The so-called early after-depolarizations ( EADs ) seen in LQTS are believed to be due to reopening of L-type calcium channels during the plateau phase of the cardiac action potential.
• The girls and Mary Ann _ who has had the disorder since birth and had fainting spells when she was younger _ now take beta blockers, the mainstay therapy that is effective in about 90 percent of LQTS subjects.
• The autosomal recessive forms of LQTS tend to have a more severe phenotype, with two variants having associated with other congenital heart disease, autism, immune deficiency and complex syndactyly ( LQT8 ) or congenital neural deafness ( LQT1 ).
• There is a condition known as the Long QT Syndrome or LQTS, a fancy medical term that means the heart is having an electrical problem _ the QT refers to a time spacing of a heartbeat which we measure on an EKG.
• Since adrenergic stimulation can increase the activity of these channels, this is an explanation for why the risk of sudden death in individuals with LQTS is increased during increased adrenergic states ( i . e ., exercise, excitement ), especially since repolarization is impaired.
• Rare diseases called channelopathies may play a roles such as long QT syndrome ( LQTS ), Brugada syndrome CPVT ( catecholaminergic polymorphic ventricular tachycardia ), PCCD ( progressive cardiac conduction defect ), early repolarisation syndrome, mixed sodium channel disease, and short QT syndrome.
• Mary Ann was wondering how she was going to tell Dave _ who in his own words was " addicted " to the girls'running and was at every meet with a stopwatch and chart _ that the three women in his life all had LQTS.
• The second case report, published in the December 1986 issue of " Zhonghua Xin Xue Guan Bing Za Zhi ", describes four cases, men, women, adults and adolescents, who were put on primidone for LQTS . The 2002 case focuses on hypocalcemia stemming from such treatment in an adolescent male.
• They were told the twins _ and 41-year-old Mary Ann _ suffered from Long QT Syndrome ( LQTS ), a rare abnormality of the heart's electrical system which brings on rapid, chaotic heart rhythms ( arrhythmia ) and can lead to sudden loss of consciousness and, sometimes, may cause sudden cardiac death.
• "' Long QT syndrome "'( "'LQTS "') is a rare congenital and inherited or acquired heart condition in which delayed repolarization of the heart following a heartbeat increases the risk of episodes of " torsades de pointes " ( TdP, a form of sudden death due to ventricular fibrillation.
