1. In patients with recurrent vasovagal syncope, current conventional therapy will fail in 40%, after 1 year follow-up.
2. In patients with recurrent vasovagal syncope, treated with conventional therapy and training in physical counterpressure manoeuvres, failure rate will be reduced to 20% (50% reduction) and Quality of Life will improve significantly.
3. In the subgroup of patients with recurrent vasovagal syncope, refractory to training in physical counterpressure manoeuvres, Midodrine therapy will lead to a recurrence rate of less than 20% and will improve Quality of Life significantly.
