In people with recurrent vasovagal syncope, diagnostic accuracy can often be improved with one of the following diagnostic tests:

A tilt table test (results should be interpreted in the context of patients clinical presentations and with an understanding of the sensitivity and specificity of the test)
Implantation of an insertable loop recorder
A Holter monitor or event monitor
An echocardiogram
An electrophysiology study

Treatment
Treatment for reflex syncope focuses on avoidance of triggers, restoring blood flow to the brain during an impending episode, and measures that interrupt or prevent the pathophysiologic mechanism described above. Lifestyle changes
The cornerstone of treatment is avoidance of triggers known to cause syncope in that person. However, research has shown that people show great reductions in vasovagal syncope through exposure-based exercises with therapists if the trigger is mental or emotional, e.g., sight of blood. However, if the trigger is a specific drug, then avoidance is the only treatment. A technique known as "applied tension" may be additionally useful in those who have syncope with exposure to blood. The technique is done by tightening the skeletal muscles for about 15 seconds when the exposure occurs and then slowing releasing them. This is then repeated every 30 seconds for a few minutes. Because vasovagal syncope causes a decrease in blood pressure, relaxing the entire body as a mode of avoidance is not favorable. A person can move or cross their legs and tighten leg muscles to keep blood pressure from dropping so significantly before an injection.
Recent research by Krystel R. Huxlin and others on the relearning of complex visual motion following V1 damage has offered potentially promising treatments for individuals with acquired cortical blindness. These treatments focus on retraining and retuning certain intact pathways of the visual cortex which are more or less preserved in individuals who sustained damage to V1. Huxlin and others found that specific training focused on utilizing the "blind field" of individuals who had sustained V1 damage improved the patients ability to perceive simple and complex visual motion. This sort of relearning therapy may provide a good workaround for patients with acquired cortical blindness in order to better make sense of the visual environment. See also
