How is the condition diagnosed?

Diagnosis of fainting starts with a medical history and physical exam. This may be all that is needed to make the diagnosis and determine the cause. The healthcare provider may order one or more of the following tests:

  • blood tests, including a blood glucose test
  • a cardiac catheterization, which shows blood flow through the heart
  • a cerebral angiogram, which shows the blood flow to the brain
  • a chest X-ray
  • a cranial CT scan, which can show abnormalities in the brain
  • an electrocardiogram, or ECG, which shows the electrical activity of the heart
  • a tilt table test, which detects drops in blood pressure when a person stands up
