Tilt-Table Test
Commonly used to diagnose individuals who have experienced periodic loss of consciousness or recurrent fainting spells (syncope), the tilt-table test checks for changes in heart rate and blood pressure when the patient’s body position is changed.
How It Works
During the test, the patient is strapped to the table and mechanically tilted to an upright position. While in this position for 20 to 30 minutes, the patient’s pulse rate and blood pressure are monitored. An electrocardiogram or tests for blood oxygen saturation may also be performed.
During an upright tilt, a patient’s cardiovascular system is expected to adjust itself in order to prevent blood volume from pooling in the lower extremities. This happens quickly and without a significant drop in blood pressure in normal individuals. If this does not occur, the patient is often diagnosed with one of two varieties of syncope (orthostatic hypotension or vasovagal syncope) and a treatment plan is developed.
