What is a tilt test?
A brief loss of consciousness is called fainting.
Fainting can be a sign of a life-threatening disease, or it can have many different causes, such as excessive heat, sweating, and stress. Fainting occurs when blood pressure is too low and cannot deliver as much oxygen to the brain as the heart's place.
The tilt test is a method used to determine the causes of fainting. It is distinctive from other causes of fainting. It gives information about the sudden decrease in blood pressure with the enlargement of the vessels and the resulting fainting. Fainting that occurs when blood flow to the brain stops is called vasovagal fainting. Tilt test is also done to detect vasovagal fainting.
