title: Ambulatory monitoring of panic patients during regular activity: a preliminary report.
abstract: Ten patients with panic disorder and 10 matched control subjects were compared as to their blood pressure and heart rate during regular daily activity. Physiological responses were monitored by ambulatory recorder, and subjective reports of mood were collected. Data were analyzed controlling for activity and stress level of the subjects. Diastolic blood pressure emerged as a possible discriminatory factor between the groups. A trend for higher heart rate occurred in the panic group. In behavioral terms, panic patients tended to avoid anxiety-provoking situations, resulting in anxiety ratings comparable to those of the control group. Thus, recorded physiological differences between the groups may reflect heightened baseline autonomic activity in panic patients.
