Head Up Tilt Test (HUTT)

Transcript of the video: Head up tilt test, is usually done for the evaluation of recurrent syncope. Sometimes, head up tilt test, also known in short as HUTT, is also done for the evaluation of postural orthostatic tachycardia syndrome, POTS, a condition in which there is tachycardia on standing up, without a fall in blood pressure. In usual syncope, there could be a fall in blood pressure, bradycardia, and there are various types, which will be described. There are various protocols for head up tilt test, which are followed in different institutions. Basically you need a tilt-table, in which the person is lying down first and observed for some time and then a tilt is given. Usually, the initial tilt given is 70 degrees. So, in case of syncope, this person can fall off. To prevent that, the person is strapped on to the tilt table before the onset of the test. And the basic principle is to observe the heart rate and blood pressure during the procedure. Ideally, a beat to beat pressure has to be monitored using a finger blood pressure or invasive blood pressure monitoring. Finger blood pressure monitoring is costly and invasive blood pressure is an invasive procedure is invasive, and not ideal in a person with syncope who can develop syncope with the procedure itself! So, there are various protocols. And sometimes, challenge with nitroglycerine or isoprenaline may be needed to induce syncope, if syncope doesn’t occur during the tilt table test without medications.
