2024年7月19日 · Long QT syndrome (LQTS) is a heart rhythm disorder that causes fast, chaotic heartbeats. The irregular heartbeats can be life-threatening. LQTS affects the electrical signals that travel through the heart and cause it to beat.

Long QT syndrome is principally diagnosed by measuring the QT interval corrected for heart rate (QTc) on a 12-lead electrocardiogram (ECG). Long QT syndrome is associated with a prolonged QTc, although in some genetically proven cases of LQTS this prolongation can be hidden, known as concealed LQTS. [23]

2023年3月20日 · Long QT syndrome is a problem with the electrical system in your heart taking too long to recharge. This issue can lead to a life-threatening type of abnormal heart rhythm. People can inherit or acquire long QT syndrome.

2022年12月26日 · The prevalence of congenital causes, also known as Long QT syndrome (LQTS), is difficult to estimate but may be expected in 1 in 2,500 to 1 in 10,000 individuals. It is more common in females and usually presents with cardiac events in childhood, adolescence, or early adulthood.

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.

2022年3月24日 · Long QT syndrome (LQTS) is a type of conduction disorder. A conduction disorder is a problem with the electrical system that controls your heartbeat. Learn about the causes, symptoms, and treatments for LQTS.

2024年7月19日 · Tests are done to check the health of the heart and confirm long QT syndrome (LQTS). A prolonged QT interval is an irregular heart rhythm. It is a change in how the heart's bottom chambers send signals. In a prolonged QT interval, it takes longer than usual for the heart to recharge between beats.

2024年5月23日 · Long QT syndrome (LQTS) is an uncommon disorder where your heart takes longer than usual to recover after each beat. It affects one in 5,000 people and can raise the risk of “torsades de...

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 …

Long QT syndrome (LQTS) is a rare heart condition that's usually inherited. It can cause serious problems with your heart rhythm, but there are things you can do to reduce the risk. Long QT syndrome can cause heart palpitations, where you suddenly feel your heart beating irregularly or faster than usual.
