Current treatment of recurrent vasovagal syncope: between evidence-based therapy and common sense.
Vasovagal syncope is very frequent and benign and the vast majority of subjects do not need any specific treatment, but only reassurance and education. An unknown but small percentage of patients require specific treatment when syncope is very frequent or is responsible for major trauma. For these patients, there are some evidence-based therapies available and some first-line treatments appear to be established. The therapeutic choice mainly depends on the presence and duration of prodromal symptoms. In subjects aged < 70 years with well recognizable prodromes, the first-line treatment is counterpressure manoeuvres. In patients with no or minimal prodromes, but with tilt testing and carotid sinus massage (CSM) both positive, cardiac pacing appear to be the first-line therapy. However, an area of uncertainty remains, represented by patients with no or minimal prodromes and negative CSM. For these patients, appropriate treatment (drugs, tilt training, cardiac pacing, relaxation-based treatment) can be chosen by considering the clinical context, the risk of trauma and possible comorbidities, in addition to utilizing the little or controversial knowledge available, as well as common sense.
