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. [4]
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 ...
Jervell and Lange-Nielsen syndrome (JLNS) is a rare type of long QT syndrome associated with severe, bilateral sensorineural hearing loss. [2] Those with JLNS are at risk of abnormal heart rhythms called arrhythmias , which can lead to fainting , seizures , or sudden death.
After surviving a cardiac arrest at just 24, Brittany Williams is on a mission to educate people about heart health and CPR. She also shares the warning sign that she dismissed.
Some causes listed include deaths also included in more specific subordinate causes, and some causes are omitted, so the percentages may only sum approximately to 100%. The causes listed are relatively immediate medical causes, but the ultimate cause of death might be described differently.
Torsades de pointes is associated with long QT syndrome, a condition whereby prolonged QT intervals are visible on an ECG. Long QT intervals predispose the patient to an R-on-T phenomenon , wherein the R-wave, representing ventricular depolarization, occurs during the relative refractory period at the end of repolarization (represented by the ...
