Long QT syndrome (LQTS) is a condition affecting repolarization (relaxing) of the heart after a heartbeat, giving rise to an abnormally lengthy QT interval. [7] It results in an increased risk of an irregular heartbeat which can result in fainting, drowning, seizures, or sudden death. [1]
Andersen–Tawil syndrome, also called Andersen syndrome and long QT syndrome 7, is a rare genetic disorder affecting several parts of the body. The three predominant features of Andersen–Tawil syndrome include disturbances of the electrical function of the heart characterised by an abnormality seen on an electrocardiogram (a long QT interval) and a tendency to abnormal heart rhythms ...
The term "torsades de pointes" is translated from French as "twisting of the peaks" because the complexes appear to undulate, or twist around, the EKG baseline. TdP can be acquired by inheritance of a congenital long QT syndrome, or more commonly from the ingestion of a pharmacologic drug. During TdP episodes, patients have a heart rate of 200 ...
Long QT syndrome, or LQTS, is when somebody’s QT interval is longer than normal, which should typically be less than half of a cardiac cycle. In fact, for a heart rate of 60 beats per minute, the QT interval’s generally considered to be abnormally long when it’s greater than 440 milliseconds in males or 460 milliseconds in females.
Goals of physical therapy treatment include improving and maintaining function by addressing impairments in mobility, posture, cardiovascular endurance, coordination, and balance. [9] A physical therapist can also fit braces, casts, and assistive devices as necessary to those with Rett syndrome to address bony malformations, and stabilize ...
Just as with the congenital causes of the Long QT syndrome, the acquired causes may also lead to the potentially lethal arrythmia known as Torsade de Pointes. Treatment is straightforward - replace any deficient electrolytes if present and stop any culprit drugs if the patient is using one (or more).
Romano–Ward syndrome is a descriptive term for a group of subtypes of long QT syndrome, specifically subtypes LQT1-6 and LQT9-16. [8] Several subtypes of Romano–Ward syndrome have been described based on the underlying genetic variant. [5] These subtypes differ in clinical presentation and their response to treatment.
The risk of arrhythmias is higher for those with Jervell and Lange-Nielsen syndrome than other forms of long QT syndrome. [10] Although this risk is dependent on the underlying genetic defect and degree of QT prolongation, without treatment more than 50% of those affected will die before the age of 15. [11]
