Because this procedure is done to evaluate your fainting spells, you may feel lightheaded or dizzy at times during the procedure and you may even faint.

Some patients may experience some minor back discomfort while lying on the hard surface of the tilt table.

If a drug is used to lower your blood pressure, you may also feel palpitations or your heart pounding when the drug is given.

Many patients who have a positive test, meaning that they fainted during the procedure, feel a little unsettled and sometimes queasy for the first few minutes after the test. The vast majority of patients will return to feeling completely normal within 5 to 10 minutes after the test. Rarely, a patient may continue to experience weakness or fatigue for a longer period of time after the test. Patients that have a negative test, meaning that they did not faint, often report that the test was tiring but otherwise felt fine.
