Tilt Table Test

The tilt table test is a medical procedure used to diagnose and manage certain types of fainting spells or syncope, particularly those related to abnormal heart rate or blood pressure regulation.

Purpose

The primary purpose of the tilt table test is to assess how the body responds to changes in position, specifically from lying down to standing upright. This helps healthcare providers identify underlying conditions that may be contributing to fainting episodes.

Procedure

During a tilt table test, the patient lies on a special table that can be tilted to different angles. The patient is secured to the table with straps to prevent falling. The procedure typically involves the following steps:

• The patient lies on the table and is connected to monitoring equipment, such as an electrocardiogram (ECG) and blood pressure monitor.
• The table is slowly tilted upwards to a 60-80 degree angle, simulating a standing position.
• The patient remains in this position for 10-30 minutes while their heart rate, blood pressure, and other vital signs are monitored.
• If the patient experiences symptoms or faints during the test, the table is immediately returned to a horizontal position.

Indications

The tilt table test is commonly used to diagnose and manage conditions such as:

• Neurally mediated hypotension (NMH), also known as vasovagal syncope
• Postural orthostatic tachycardia syndrome (POTS)
• Orthostatic intolerance

Risks and Complications

The tilt table test is generally a safe procedure, but it may cause:

• Dizziness or lightheadedness
• Fainting or near-fainting episodes
• Pain or discomfort from the straps or table

Interpretation of Results

The results of a tilt table test are interpreted based on the patient's symptoms and physiological responses during the procedure. A positive result may indicate:

• A drop in blood pressure or heart rate
• An increase in heart rate or other abnormal heart rhythms
• The presence of symptoms such as dizziness, lightheadedness, or fainting

Limitations

The tilt table test is not suitable for all patients and may have limitations, including:

• Pregnant women or those with certain medical conditions may require alternative diagnostic tests.
• The test may not accurately diagnose all types of syncope or fainting disorders.
