Currently it is not possible to cure LQTS, however the various therapies make it possible to improve the health of the patients, the more so as some manage to carry out a life very close to the normal.

The choice of a processing is always according to the symptoms, of intolerances and the counter-indications which the patient can have.

The treatment more prescribed is the catch of beta-blockers, these drugs are effective in 85 to 90% of the cases among patients reached of the LQTS. The beat-blockings cause to block the action of the nervous system sympathetic nerve on the heart. The PROPANOLOL is the drug more employed, but also the NADOLOL.

Unfortunately these drugs are not appropriate for all, if they are badly tolerated or indicated against for the patient, in this case another therapy will be advised to him, possibly Sympathectomie (Denervation Sympathique Cardiac Left " DSCG "). The association of beta-blockers and the pause of a Pacemaker " PM " can be considered in the case of bradycardia or cardiac installation. If the case is more complex, that there is a heart risk of failure, that the patient does not tolerate the beta-blockers ; the "DSCG " more the establishment of a defibrillator proves to be essential.

In spite of a " DSCG " and the catch of beta-blockers, when the syncopes persist, a sort-therapy will be associated with individually, the possibility of a denervation right cardiac sympathetic nerve is not excluded. The sort-therapies can be different from one patient to another, the symptoms and reactions are varied, only a specialist is able to evaluate the gravity of the disease, to estimate the risks and to propose a suitable therapy of them.
