The tilt table test is an exam to observe the variations in heart rate and blood pressure from beat to beat, in relation to changes in inclination, which allows determining the possible causes of a loss of consciousness (syncope) and system disorders autonomic nervous.
To carry out this test, a special (tilting) table is used on which the patient lies down, intravenous infusion is established with glucose solution and is held by means of safety straps on the chest, arms and legs. This table allows moving from a horizontal to a vertical position between 60 to 80 degrees, without any effort for the patient, where it remains for 20 to 30 minutes with continuous monitoring, during which time the doctor must be informed if symptoms such as fatigue occur. , dizziness, shortness of breath, paleness, sweating and even syncope.
If at the end of this phase, there were no clinical symptoms or alterations in blood pressure or heart rate, the patient returns to the initial position and a second phase begins, which will last 15 minutes, after administering a drug in spray or tablet under the tongue, which induces a stress situation waiting for its hemodynamic and neurocardiogenic response when performing the procedure again.
If the patient presents significant alterations in blood pressure, heart rate, lightheadedness, relaxation of the sphincters or syncope, before the end of the phase, the tilting table immediately returns to its initial position and the recovery process begins. Otherwise, the test continues until it is complete. The tilt table returns to its starting position, vital signs are monitored, and the exam is complete.
