How tilt table testing is done

Typically, people are strapped to a motorized table and remain lying flat for 15 minutes. Then they are tilted head up at a 60° to 80° angle for 45 minutes to see whether they feel faint or their blood pressure and heart rate decrease. If blood pressure does not decrease, isoproterenol (a drug that stimulates the heart) is injected into the person's vein in a dose large enough to accelerate the heart rate by 20 beats per minute, and the test is repeated.
