Almost everytime<unk> s require no treatment, especially if there are limited symptoms. The most effective treatment is the elimination of triggers (particularly stopping the use of substances such as caffeine and certain drugs, like tobacco). If frequent, it’s possibile to use: * Medications * Antiarrhythmics: these agents alter the electrophysiologic mechanisms responsible for<unk> s. In CAST study of survivors of myocardial infarction encainide and flecainide, it was shown that, though those drugs could suppress<unk> , they also increased the risk of death. However, while moricizine increased the death rate when used with diuretics, it reduced the frequency of deaths when it was used alone. * Beta blockers * Calcium channel blockers * Electrolytes replacement * Magnesium supplements (e.g. magnesium citrate, orotate, Maalox, etc.) * Potassium supplements (e.g. chloride potassium with citrate ion) * Radiofrequency catheter ablation treatment. It is advised for people with<unk>  dysfunction and/or tachyarrythmia or very frequent<unk>  (>20% in 24 h) and normal<unk>  function. This procedure is a way to destroy the area of the heart tissue that is causing the irregular contractions characteristic of<unk> s using radio frequency energy. * Implantable cardioverter-defibrillator * Lifestyle modification * Frequently stressed individuals should consider therapy, or joining a support group.
