hyperventilation syndrome

a complex of symptoms that accompany hypocapnia caused by hyperventilation, including palpitations, shortness of breath, lightheadedness, profuse perspiration, and tingling sensations in the fingertips, face, or toes; prolonged overbreathing may result in vasomotor collapse and loss of consciousness. Hyperventilation unrecognized by the patient is a common cause of the subjective somatic symptoms associated with chronic anxiety or panic attacks (see panic disorder, under disorder).
