Význam LQT v angličtině Jak bylo uvedeno výše, LQT se používá jako zkratka v textových zprávách pro reprezentaci Syndrom dlouhého QT. Tato stránka je o zkratu LQT a jeho významu jako Syndrom dlouhého QT. Uvědomte si prosím, že Syndrom dlouhého QT není jediný význam pro LQT Romano-Ward syndrome is the most common form of inherited long QT syndrome. Symptoms include arrhythmia, fainting, cardiac arrest, and sudden death. There are six different types of this syndrome, long QT 1 through 6. Each type is caused by a change in a different gene. The most prevalent form of long QT syndrome is long QT type 1 Alexis Holmgren, LQTS Type 5 Alexis Holmgren, a 20-year old from Central Alberta, Canada, was diagnosed with LQTS Type 5 when she was 12. Growing up she experienced multiple fainting spells after basketball practice and three near-drowning events between the ages of 10 and 11, but as she reveals, LQTS does not define her The Jervell and Lange-Nielsen syndrome is rare. People with this syndrome have a very long QT interval and are also deaf. The Jervell and Lange-Nielsen syndrome is an autosomal recessive inherited condition - meaning that you need to inherit two abnormal genes, one from each parent, to get this syndrome

Long QT syndrome - Diagnosis and treatment - Mayo Clini

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 gene mutations (changes). It can also be acquired (noninherited) and may be brought on by certain medicines and other medical conditions Long QT syndrome (LQTS) is a condition which affects repolarization of the heart after a heartbeat. It results in an increased risk of an irregular heartbeat which can result in palpitations, fainting, drowning, or sudden death. These episodes can be triggered by exercise or stress. Other associated symptoms may include hearing loss Long QT syndrome (LQTS) is an abnormal feature of the heart's electrical system that can lead to a potentially life-threatening arrhythmia called torsades de pointes (pronounced torsad de pwant). Torsades de pointes may result in syncope (fainting) or sudden cardiac death. What happens during LQTS Long QT Syndrome (LQTS) is a medical condition resulting from an abnormality in the electrical system of the heart. The QT interval refers to a specific measurement on the electrocardiogram, the record of the electrical activity of a person's heart. A QT interval is measured in seconds or in milliseconds Long QT syndrome (LQTS) is a disorder that can cause erratic and irregular heartbeat. Our heart is controlled by an electrical system that helps determine how fast our heart should beat (your heart rate). It does this by using electrical signals to coordinate the heart muscles to beat together so the heart can pump blood efficiently

Long QT Syndrome: Symptoms, Causes, Treatment, and Life

Long QT syndrome (LQTS) is a rare disorder of the heart's electrical system that can lead to dangerous heart rhythms, fainting, and sudden cardiac arrest. At Stanford, our internationally renowned electrophysiologists have the skill and experience to provide superior care for this complex condition Long QT syndrome (LQT) represents a heterogeneous family of cardiac electrophysiologic disorders characterized by QT prolongation and T-wave abnormalities on the electrocardiogram. It is commonly associated with syncope, however, sudden cardiac death can occur due to torsades de pointes As with most forms of LQT syndrome, characteristic triggering events are associated with precipitating cardiac events. LQT1, for example, seems to be triggered by exercise, particularly swimming, and by emotional stress. Incredibly, 99% of cardiac events occurring while swimming involve individuals with LQT1 Long QT syndrome (LQTS) is a disorder of ventricular myocardial repolarization characterized by a prolonged QT interval on the electrocardiogram (ECG) (waveform 1) that can lead to symptomatic ventricular arrhythmias and an increased risk of sudden cardiac death (SCD) [ 1,2 ]

Long QT is a syndrome that can cause a disturbance in the electrical system of the heart, whilst the mechanical function of the heart can remain completely normal. Long QT may result in a very fast abnormal heart rhythm (known as an arrhythmia). This particular arrhythmia is technically known as 'Torsade de Pointes' LQT Therapeutics aims to develop a series of preclinical compounds to provide new treatment options for patients with Long QT Syndrome and other cardiac arrhythmias. LQTS is a rare genetic heart rhythm condition that causes rapid, chaotic heartbeats or arrhythmias due to a prolonged QT interval

Long QT Syndrome (LQTS) produces prolonged ventricular repolarisation -> predisposes to malignant ventricular arrhythmia Long QT syndrome (LQTS) is caused by malfunction of cardiac ion channels impairing ventricular repolarization. 1 This predisposes to the development of the polymorphic ventricular tachycardia torsade de pointes ('twisting of the points') (Fig. 1)

Congenital long QT syndrome (LQTS) is an inherited disorder affecting the heart's electrical system.It is one of the conditions associated with sudden death in young athletes. The life-threatening arrhythmias seen with LQTS are more likely to occur during exercise, so in many people with this condition exertion must be limited LQTS is an inherited or acquired disturbance of the heart's electrical system caused by abnormalities of microscopic pores, or holes, in the heart cells called ion channels. Ions such as potassium, sodium, calcium and chloride pass back and forth across the cell membrane through these channels Long QT syndrome (LQTS) is a congenital disorder characterized by a prolongation of the QT interval on electrocardiograms (ECGs) and a propensity to ventricular tachyarrhythmias, which may lead to syncope, cardiac arrest, or sudden death. (See Etiology, Prognosis, Presentation, and Workup The LQT Syndrome may be inherited or it may be induced by some medications. The LQT Syndrome is absolutely treatable and treatment saves lives.

Torsade de pointes (twisting of the points) is a particular type of polymorphic ventricular tachycardia that can be associated with LQTS. LQTS can be congenital or acquired Long QT syndrome (LQTS) is an arrhythmogenic cardiovascular disorder resulting from mutations in cardiac ion channels. LQTS is characterized by prolonged ventricular repolarization and frequently manifests itself as QT interval prolongation on the electrocardiogram (ECG). The age at presentation varies from in utero to adulthood

Congenital LQTS was first described in 1957 by Jervell and Lange-Nielsen4as an autosomal recessive cardioauditory syndrome characterized by prolonged QT interval and congenital deafness. Romano et al. 5and Ward6later described a similar syndrome involving QT interval prolongation, syncope, and sudden death but without deafness and with an autosomal dominant pattern of inheritance Long-QT (LQT) syndrome mutation carriers have higher risk of cardiac events than unaffected family members even in the absence of QTc prolongation. Changes in T-wave morphology may reflect penetrance of LQT syndrome mutations. We aimed to assess whether T-wave morphology may improve risk stratification of LQT2 mutation carriers with normal QTc.
