Testing of autonomic nervous system function; combined parasympathetic and sympathetic adrenergic function testing with at least 5 minutes of passive tilt

AI EXPLANATION: Autonomic function testing measures how well the body's involuntary nervous system regulates vital processes such as heart rate, blood pressure, and body temperature. During the test, a clinician monitors how these systems react to various stimuli, which commonly includes resting, deep breathing exercises, and lying on a motorized tilt table that safely raises you into an upright position for at least five minutes.
