What is Long QT Syndrome

Long QT Syndrome is a heart condition, that can cause chaotic outbursts of your heart beating. Leading to fainting, Seizures or even sudden death. This article is for anybody who has Long QT Syndrome or is concerned about someone who has the disorder

Inheriting Long QT Syndrome

Long QT Syndrome is inherited by a passing of relatives through a recessive trait. The heterogeneous disorder was divided into two type of syndromes. Romano-Ward Syndrome and Jervell and Lange-Nielsen Syndrome. The first type Romano-Ward type is the one that occurs in most people, Its only received through one parents genetics and you get it as a baby. Jervell and Lange-Nielsen Syndrome is the more uncommon one. Where the victim inherits the gene from BOTH parents and is likely to be born deaf.

The photo above shows a heart beat, because all the symptoms that come with Long QT syndrome come from the heart.

Fainting: One of the most common symptoms when having Long QT syndrome. When someone gets angered, excited or startled can start your heart rate to sky rocket uncontrollably. Even small things like hearing a phone ring randomly can trigger someone to faint.

Seizures: Along with fainting, your heart rate will rise chaotically and if it isn't fainting that will occur. The brain will be deprived of oxygen and a seizure will occur.

Sudden Death:When the heart does not return to its normal heart rate in time and paramedics are not contacted sudden death will occur within the person.

Treatments and Test

There are many test and treatments that can be done to keep up with Long QT Syndrome.

EKG/ECG: An ECG is a heart scan process which can determine and find out many things within in the heart. It shows your heart pattern and can determine whether you have QT syndrome or not!

Portable ECG: Like a ECG this device is portable and helps more efficiently because you can wear it throughout the day and it determines your heart pattern and shows how active you are. a Holter monitor which as well determines your heart activity

Genetic testing is also a helpful way to find out from who and when you inherited Long QT

Recent Research

Long QT Syndrome is caused by mutations in the genetic code. These mutations take place in Ion channels. Ion channels are openings in the cell that provide electrical currents that keep someones heart rate normal and steady. People with Long QT have these channels effected and cannot properly open and operate correctly. 12 major genes cause Long QT but hundreds of mutations can be found within those genes that could lead up to it. Normally a patient is only infected with one mutation. Its rare for someone to have more then one major mutations and still inherit the disorder. There is not a exact number of people recorded that have Long QT but its estimated that there's about 2,000-2,500 people worldwide effected by the syndrome.
