Overview
The head-up tilt table test mimics the orthostatic stress. The orthostatic stress results in maximal venous pooling, central hypovolaemia and peripheral provocation of vasovagal syncope.
Role in diagnosis of Neurocardiogenic Shock
In-spite of the test being positive in patients with neurocardiogenic shock, it is not considered as a gold standard for diagnosis because of its limited sensitivity, specificity and reproducibility.[1]
Depending on patient selection and protocol, the test has high sensitivity (upto 80%) but low specificity.
