Long Q-T syndrome is a disorder of the hearts electrical system. The electrical activity of the heart is produced by the flow of ions (electrically charged particles of sodium, calcium, potassium, and chloride) in and out of the cells of the heart. Tiny ion channels control this flow.
Long QT Syndrome 8 Causes, ECG Diagnosis & Treatment Jan 14, 2021 · Long QT syndrome is an inherited or acquired condition of the heart that results in abnormal heart rhythms (arrhythmias). The heart beats dangerously fast and erratically due to dysfunction in the electrical activity of the heart.
What Is It?SymptomsDiagnosisExpected DurationPreventionTreatmentPrognosisFurther InformationLong QT syndrome is an uncommon inherited condition meaning it's caused by genes passed on to you from your parents. The electrical activity of heart cells is controlled by a set of channels that pump minerals, such as sodium and potassium, in and out of cells. If you inherit genes that cause alterations in these channels, it can affect the action of heart cells.Normally, an electrical impulse starts in the sinus node, located in the upper chamber of the heart. The electrical impulse then tPeople also askHow do I know if I have long QT syndrome?How do I know if I have long QT syndrome?An ECG records your heart's rhythm and electrical activity. If you have long QT syndrome, the trace of the QT section (showing part of the heartbeat) will be longer than normal. Sometimes an exercise ECG will be needed to confirm the diagnosis.Long QT syndrome - NHS.UK

Mar 17, 2021 · Long QT syndrome (LQTS) is a genetic or acquired condition characterised by a prolonged QT interval on the surface ECG and is associated with a high risk of sudden cardiac death due to ventricular tachyarrhythmias. Mutations within 13 identified genes result in a variety of channelopathies affecting myocardial repolarisation, thus prolonging
Types of Long QT Syndrome Stanford Health CareLong QT syndrome (LQTS) is a rare disorder of the hearts 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 Genetic and Rare Diseases Information Oct 04, 2013 · Long QT syndrome is a disorder of the hearts 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).
