HUT

A test in which the patient lies flat on a table in order to identify the reason for fainting spells. The table has adjustable head and foot positions so that the effect of different positions on the patient's blood pressure, pulse, and heart rhythm can be assessed for abnormal responses, such as a marked slowing of the heart rate.
