It is therefore the investigators hypothesis that daily oral administration of the specific micronutrients combination will lead to a decrease of symptoms awareness and to a reduction of heart rhythm disturbances in adults with or without structural heart disease. The principal endpoints will be a decrease in the total score of symptoms awareness.
