Scientists have come to the conclusion that sudden deaths due to cardiac issues can be caused by genetic defects. This fact can be of immense help in trying to reduce sudden deaths in patients who have been suffering from Long QT syndrome which is an unusual and hereditary heart rhythm disorder.
Further these studies state that particular genetic mutations cause defects that can be the reason for sudden death and other cardiac ailments in the patient. These findings are particularly true of have this condition but do not exhibit any clinical symptoms and this constitutes for about 70% of the Long QT syndrome crowd.
The treatments that are presently being meted out to patients with the Long QT syndrome are the use of Beta Blockers that reduce the tension that is exerted on the heart by slowing down the heart rate and the Implantable Cardioverter Defibrillators that identify risky and irregular heart beats and exert shock on the heart to bring it back to its normal pace. The more the doctor has information about the danger, the better he will be in a position to choose the mode of treatment that the patient may require either using the ICD or the Beta Blocker.
