Summary

Content: Low blood pressure typically causes syncope blackouts because the heart cannot pump enough oxygen-rich blood to the brain. There are two main types of syncope blackouts: neurally mediated and cardiac. A neurally mediated syncope is usually benign and requires no further treatment. It could occur when a person’s blood pressure drops after they experience pain or dehydration or get up too quickly. This type of syncope tends to occur more in children and young adults. A cardiac syncope is more serious as it could signal an underlying problem with the heart. Tachycardia, bradycardia, or other types of hypotension could cause a cardiac syncope. If a person does not get treatment, they are at risk of complications or even sudden cardiac death. Treatment
A doctor may prescribe fludrocortisone to reduce blackouts
