Summaries for Long Qt Syndrome

About this section
PubMed Health : 63 About long qt syndrome: Long QT syndrome (LQTS) is a disorder of the heart's electrical activity. It can cause sudden, uncontrollable, dangerous arrhythmias (ah-RITH-me-ahs) in response to exercise or stress. Arrhythmias are problems with the rate or rhythm of the heartbeat.People who have LQTS also can have arrhythmias for no known reason. However, not everyone who has LQTS has dangerous heart rhythms. When they do occur, though, they can be fatal.

MalaCards based summary : Long Qt Syndrome, also known as romano-ward syndrome, is related to long qt syndrome 9 and long qt syndrome 13, and has symptoms including syncope An important gene associated with Long Qt Syndrome is SCN5A (Sodium Voltage-Gated Channel Alpha Subunit 5), and among its related pathways/superpathways are Adrenergic signaling in cardiomyocytes and Oxytocin signaling pathway. The drugs Histamine and Estradiol have been mentioned in the context of this disorder. Affiliated tissues include heart, testes and brain, and related phenotypes are Decreased shRNA abundance and Reduced mammosphere formation

Disease Ontology : 12 An autosomal genetic disease that is characterized by delayed repolarization of the heart following a heartbeat increases the risk of episodes of torsade de pointes (TDP, a form of irregular heartbeat that originates from the ventricles).

NIH Rare Diseases : 53 Long QT syndrome is a disorder of the heart�??s electrical activity that can cause sudden, uncontrollable, and irregular heartbeats (arrhythmia), which may lead to sudden death. Long QT syndrome can be detected by electrocardiogram (EKG). It can be caused by a variety of different genemutations (changes). It can also be acquired (noninherited) and may be brought on by certain medicines and other medical conditions.

Wikipedia : 76 Long QT syndrome (LQTS) is a condition which affects repolarization of the heart after a heartbeat. This... more...

About this section

PubMedHealth treatment related to Long Qt Syndrome: 63

The goal of treating long QT syndrome (LQTS) is to prevent life-threatening, abnormal heart rhythms and fainting spells.Treatment isn't a cure for the disorder and may not restore a normal QT interval on an EKG (electrocardiogram). However, treatment greatly improves the chances of survival.
