Tilt Table

A tilt table test is used to verify if a patient has low pressure drops associated with syncope. The heart, of a horizontal patient, pumps blood at a mean arterial pressure of 90 mmHg (12 kPa). The patient faints as soon as the tilt table goes vertical, this means the blood acceleration equal the gravitational acceleration. If the heart rate does not increase to compensate for the change in angle, at what angle would the blood be pumping one half its horizontal pressure.
