TiltTableTest

The Tilt Table Test is a diagnostic medical procedure used to evaluate the cause of unexplained syncope, also known as fainting. It helps identify whether the fainting is due to a problem with the autonomic nervous system's regulation of blood pressure and heart rate. The test involves strapping a patient to a specialized table that can be tilted to different angles. Initially, the patient lies flat, and their blood pressure and heart rate are monitored. Then, the table is tilted to an upright position, typically 60 to 80 degrees, mimicking the gravitational effects of standing. This upright posture can sometimes trigger a vasovagal or neurally mediated syncope episode in susceptible individuals. During the tilt, continuous monitoring of heart rate and blood pressure continues. If symptoms of lightheadedness, dizziness, or fainting occur, or if significant drops in blood pressure or heart rate are detected, the test is considered positive. In some protocols, a medication like nitroglycerin or isoproterenol may be administered during the tilt to try and provoke a response if it doesn't occur spontaneously. The test duration varies but is typically between 20 to 45 minutes, though it can be extended if symptoms are delayed. Based on the patient's response, the tilt table test can help physicians determine if vasovagal syncope is the cause of their fainting spells, guiding appropriate management and treatment strategies.
