A tilt table test, also known as a tilt test or passive head-up tilt test, is a diagnostic procedure used to evaluate the causes of fainting or lightheadedness. It involves tilting a patient from a lying position to an upright position while monitoring their blood pressure, heart rate, and symptoms.

During a tilt table test, the patient lies flat on a special table that can be tilted upward. Straps are used to secure the patient in place. The table is then gradually tilted to an upright position, simulating the effect of standing up. The patient remains in the upright position for a period of time while their vital signs and symptoms are monitored.

The purpose of the tilt table test is to assess the body’s cardiovascular response to changes in posture. It helps identify conditions such as vasovagal syncope, postural orthostatic tachycardia syndrome (POTS), or other forms of orthostatic hypotension.

The test is typically performed in a controlled environment, such as a specialized tilt table test lab or cardiology clinic. The patient’s blood pressure, heart rate, and electrocardiogram (ECG) are continuously monitored throughout the procedure. If symptoms such as dizziness, lightheadedness, or fainting occur, they are carefully documented.

In addition to the passive tilt table test, there may be variations where medications or additional provocations (such as nitroglycerin or isoproterenol) are used to induce specific responses in the cardiovascular system.

The tilt table test is generally considered safe, but there may be certain risks involved, such as fainting or a drop in blood pressure during the procedure. The test is typically conducted under the supervision of healthcare professionals who are prepared to manage any potential complications.

By evaluating the body’s response to postural changes, the tilt table test helps healthcare providers diagnose and understand the underlying causes of unexplained fainting or lightheadedness. The results of the test can guide further treatment and management strategies for the patient.
