Syncope, also known as fainting and passing out, is an abrupt, yet temporary loss of consciousness due to a drop in blood pressure. Causes include stress, pain, dehydration, exhaustion, sweating, heart disorders, metabolic disorders, and lung disorders.
Symptoms of syncope include:
- Abnormal heart rhythm (arrhythmias)
- Blurry vision
- Difficulty speaking
- Hypotension, or low blood pressure
- Loss of movement
Diagnosis of Syncope
Your UT Southwestern Medical Center doctor may perform several tests to diagnose syncope. Common diagnostic tests include:
- Cardiac catheterization
- CT scan to check for possible neurologic causes
- Holter monitor
- Stress test
- Tilt table test to detect a drop in heart rate and blood pressure
Treatment for Syncope
If someone experiences syncope, treatments include:
- Roll the person onto his back and keep the airway open.
- Raise his legs above his head and loosen clothing.
- Initiate CPR if breathing and pulse are weak or not present.
