During this 15 minute assessment, specialized monitoring technology with a blood pressure cuff, electrodes, pulse oximeter and temperature sensor measures average heart rate, blood pressure, blood oxygen saturation, and body temperature with patient at rest and in various states of physiological stress, and while breathing deeply, performing a heart straining breath technique called Valsalva maneuver and standing for five minutes. The system then uses an algorithm to calculate sympathetic and parasympathetic activity, which the practitioner interprets. This diagnostic test is expected to become a part of the annual exam.
