Diagnosing Syncope

Your doctor will ask you about your fainting episode and health history. You will also be examined. And your doctor may order one or more tests.

Electrocardiogram

History and Physical

You may be asked about:

• Where and when you fainted, and how long the episode lasted

• How you felt just before and right after you fainted

• Any family history of heart disease or fainting

• Any cardiac or neurological problems you may have

• Any medications you may be taking

Your doctor will examine you. Your doctor may:

• Check your blood pressure several times

• Listen for any murmurs or unusual heartbeats

• Examine your eyes, reflexes, and the movement of your limbs

Tilt table testing

Testing

Electrocardiogram (ECG): This can help your doctor find a slow or a fast heartbeat.

Holter and Event Monitoring: For Holter monitoring, a portable ECG monitor records your heartbeat for 24 hours. An event recorder is similar, but worn for several weeks.

Echocardiogram: This test takes pictures of your heart. It can show heart valve or heart function problems. Or it can reveal damage from a heart attack.

Electrophysiology Studies (EPS): These help your doctor find weak or damaged electrical pathways that make your heart beat too fast or too slow. These studies help your doctor determine the exact cause of your heart rate problem and how to treat it.

Tilt Table Testing: Tilt table testing helps show if changes in your body position affect your heart rate and blood pressure.
