Short QT syndrome (SQT) is a very rare genetic disease of the electrical system of the heart, and is associated with an increased risk of abnormal heart rhythms and sudden cardiac death. [1] The syndrome gets its name from a characteristic feature seen on an electrocardiogram (ECG) – a shortening of the QT interval .
In 20% of cases, no cause of death can be found, even after extensive examination. [13] Sudden arrhythmic death syndrome in alcohol abuse is a significant cause of death among heavy drinkers, characterized by older age and severe liver damage, highlighting the need for family screening for heritable channelopathies.

If reversed, coma, persistent vegetative state, post-cardiac arrest syndrome; if not reversed, death: Usual onset: The risk of onset increases with age [3] Causes: Coronary artery disease, congenital heart defect, major blood loss, lack of oxygen, electrical injury, very low potassium, heart failure, myocardial infarction: Diagnostic method
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.
Abnormalities in this system occur in relatively rare genetic diseases such as Long QT syndrome, Brugada syndrome, and Catecholaminergic polymorphic ventricular tachycardia, all associated with sudden death. Consequently, autopsy-negative sudden cardiac deaths (no physical abnormalities identified) may comprise a larger part of the ...
The most striking sign of Timothy syndrome type 1 is the co-occurrence of both syndactyly (about 0.03% of births) and long QT syndrome (1% per year) in a single patient. . Other common symptoms include cardiac arrhythmia (94%), heart malformations (59%), and autism or an autism spectrum disorder (80% who survive long enough for evaluati
Her official cause of death was cardiac arrhythmia and severe asthma, the latter of which she had never been diagnosed with. Her family had independent experts examine tissue samples of her heart muscle and they concluded that the most likely cause of death was a missed diagnosis of ACM.
