The System is also assisting researchers in defining new pharmaceutical endpoints in a range of disorders such as * chronic heart failure * generalized anxiety disorder * respiratory sinus arrhythmia during daily activity * heart rate variability in coronary artery disease * anxiety * adolescent post traumatic stress disorder * respiratory sinus arrhythmia during daily activity * chronic obstructive pulmonary disease * panic * attention deficit hyperactivity disorder * apnea in post-acute cerebral vascular accident * autism * medically-unexplained syndrome * syncope * and sleep.
