A previous report2 dealt with the problem of describing pattern in repeated measurements and presented the results of a factor-analytic investigation of heart-rate patterns in a group of anxious patients. The present study extends this technique of factor analysis of a temporal pattern of cardiovascular response to include patterns of systolic and diastolic blood pressure, as well as heart rate in a second group of subjects.
As in the previous report, this research was part of a larger study on the effects of experimentally produced anxiety conducted at the Institute for Psychosomatic and Psychiatric Research and Training of Michael Reese Hospital. The rationale and methods of these studies were described in an early paper3; a number of additional reports have since appeared.
Subjects and Procedure
The subjects were 10 adult male psychiatric patients. Most of the group had recently been admitted to a nearby state
