Other diagnostic tests and procedures include the following:

  • Head-up tilt-table test - Useful for confirming autonomic dysfunction and can generally be safely arranged on an outpatient basis
  • Electroencephalography (EEG) - Can be performed at the discretion of a neurologist if seizure is considered a likely alternative diagnosis
  • Stress test - A cardiac stress test is appropriate for patients in whom cardiac syncope is suspected and who have risk factors for coronary atherosclerosis
  • Carotid sinus massage (to diagnose carotid sinus syncope)
