Regular blood pressure measurements are critically important for diagnosing low blood pressure (hypotension). Consistently having blood pressure below 90/60 mmHg, accompanied by symptoms such as physical weakness and fatigue, usually indicates hypotension. However, diagnostic confusion can arise as symptoms like sudden fainting can be mistaken for other conditions such as epilepsy. To make this distinction, a Tilt Table test is performed.
In the Tilt Table test, the patient is secured with safety straps to a special table whose head section can be elevated. First, blood pressure and pulse are measured while the patient is lying down. Then, the table is tilted for a certain period, with the patient's head elevated 60-70 degrees upwards. Blood pressure and pulse are monitored again in this position. In some cases, a vasodilator medication may be administered before the test. For patients with a history of fainting, a controlled fainting episode may be triggered in a hospital setting during the test. The purpose of this test is to definitively differentiate whether the patient's fainting is due to low blood pressure or another cause.
