What are the risks associated with this procedure?
Although safe, cardiac catheterization with hemodynamic assessment carries some risks, such as: Bleeding Infection Allergic reactions to contrast dye Complications related to catheter
Is cardiac catheterization with hemodynamic assessment painful?

How quickly does one recover from syncope?

How much is the sensitivity of the head-up tilt test in patients with syncope?
Tilt head test has an estimated sensitivity of 25% to 75% and specificity of 90% to 100%.
Is there administration of any medication during the test?
If no symptoms are seen, medicine to increase heart rate may be given during the procedure.
Is there any difference between individuals with positive and negative tests?
There is no significant difference between them regarding age, sex, supine systolic blood pressure, number of syncopal attacks in patients with syncope history, underlying heart disease, ejection fraction, or type of fascicular block.
Who conducts the test?
A cardiac physiologist conducts the head-up tilt test.
What preparations are needed before the test?
The patient needs to eat a light meal 2 to 3 hours before and then not eat until after the test.
Why is GNT spray given during the head-up tilt test?
GNT spray is given under the tongue during the test to elicit a vasovagal response, which is known to induce venous dilation.
Where is the head-up tilt test performed?
