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 (LQTS) is a cardiac conduction disorder characterized by prolongation and increased dispersion of ventricular repolarization, manifested by lengthening of the QT interval on the surface electrocardiography (ECG).

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.

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. Most people take medication for long QT. Others may need a device or surgery to lower their risk of abnormal heart rhythms.

Long QT syndrome is a rare heart disorder that upsets the electrical activity of your heart. This electrical disruption can cause an abnormal heartbeat and even sudden death. Family history of long QT syndrome is the main risk factor for developing the condition.

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.

Long QT syndrome (LQTS) is a cardiac electrophysiologic disorder, characterized by QT prolongation and T-wave abnormalities on the ECG that are associated with tachyarrhythmias, typically the ventricular tachycardia torsade de pointes (TdP).

2003年2月20日 · Long QT syndrome (LQTS) is characterized by QT prolongation and T wave abnormalities on EKG. LQTS predisposes individuals to a significant risk of life-threatening arrhythmic events, especially in young individuals.

2022年10月7日 · More than 15 forms of LQTS have been described, but most cases fall into 3 subgroups: Long QT syndrome type 1 (LQTS1): Loss-of-function mutation of gene KCNQ1, which encodes an adrenergic-sensitive Kv7.1 channel responsible for the …

2023年11月27日 · Long QT syndrome (LQTS) affects the normal electrical activity of your heart, causing it to take longer than usual to recharge between beats. Learn more.
