Now, let’s discuss what causes such problem as the vasovagal syncope. It is important to understand why the reflex syncope happens before discussing the possible reasons. One of the parts of our nervous system is responsible for the heart rate and blood pressure. If this critical part stops working properly as a result of some impulse or external irritator like danger, it turns to the vasovagal syncope.
There are several classical triggers as well as less expected factors. The most common causes are the straight-standing poses/gestures, the presence of blood running out of some wounds or injuries, being scared of the body traumas, heat exposure, and straining.
