Head-up Tilt Test in Vasovagal Syncope: For which Purposes? For whom?

This has made it possible to better understand various aspects of the pathophysiological mechanisms involved in vasovagal syncope, such as the behavior of the vascular tree, changes in volemia, myocardial contractility disorders preceding the episode, variations in cathecholamine secretion, and modifications in the variability of heart rate or sympathetic traffic, among others.

For this reason, it is important to have specific data on the characteristics and prognosis of vasovagal syncopal episodes in the pediatric population in order to establish a strategy in which only tests that contribute useful information for diagnostic, therapeutic, and prognostic management are made.

Tilt Table Test

You may feel tired and a little sick to your stomach right after the test. Nevertheless, the absence of a positive response to TTT, especially in patients without heart disease and with a normal ECG, does not allow a vasovagal cause to be excluded. On the contrary, they suggest that TTT could be useful in patients with a larger number of previous syncopes, either to confirm the diagnosis or to identify patients with severe and recurrent episodes and a cardioinhibitor response to TTT, who could benefit from permanent cardiac pacing.

What do you think is causing me to feel lightheaded or faint? For which Purposes? Therefore, the presence of a positive response to TTT in patients without heart disease and with a normal ECG, or in patients with heart disease in which a cardiogenic cause of the syncopal episodes has been reasonably excluded, can be considered diagnostic of a vasovagal origin.
