long QT syndrome is uncommon, affecting approximately 1 in every 2,000 human beings.

symptoms of long QT syndrome
a few people with long QT syndrome have no symptoms. they'll simplest become aware about their condition after having an electrocardiogram (ECG) for some other purpose.

folks who do have signs normally experience:

blackouts or fainting, due to the fact the coronary heart has stopped pumping blood well and the mind is briefly starved of oxygen – the coronary heart's rhythm returns to ordinary inside a minute or  and the person regains consciousness
seizures, which now and again occur in place of a blackout while the brain is starved of oxygen
heart palpitations, whilst the coronary heart is beating in a fast or unpredictable way
these symptoms can start unexpectedly and can be induced via:

a sudden noise – consisting of an alarm
strenuous workout – mainly swimming
a gradual heart rate in the course of sleep
threat of demise
The coronary heart typically returns to its everyday rhythm after it is been beating abnormally.

but if it continues to conquer abnormally and isn't dealt with in time with a defibrillator, the coronary heart may not pump and the individual will die. that is referred to as cardiac arrest, and the coronary heart rarely returns to everyday if it is not electrically corrected with shock.

Dial 999 to invite for an ambulance if someone with lengthy QT syndrome unexpectedly collapses and does not regain attention. if you're able to, carry out cardiopulmonary resuscitation (CPR) until clinical help arrives.

long QT syndrome is usually as a result of a faulty gene inherited from a determine.

The odd gene influences the proteins that make up the ion channels regulating energy within the heart. The ion channels may not work properly, or there may not be sufficient of them, which disrupts the heart's electrical activity.

certain medicines can also cause lengthy QT syndrome, including a few varieties of:

heart medicines
however drug-brought about lengthy QT syndrome tends to most effective affect those who already have a propensity to expand the condition.

Cardiac risk within the young has published a listing of medications that human beings with lengthy QT syndrome need to keep away from.
