A monitoring system for detecting and processing parameters affecting the cardiovascular system of a subject, and which includes a conventional Holter EKG recorder for long term electrocardiogram monitoring of the subject. In addition, the monitoring system includes sensors responding to certain physical activities and emotional states of the subject for generating electric signals representative of such activities and states. These electric signals are recorded in a separate recorder, or along with the EKG signals in the Holter recorder. The monitoring system includes a signal processor for correlating the signals from the sensors with predetermined coefficients so as to yield statistical data related to the physical activities and emotional states of the subject and to correlate signals representative of such activities and states with the EKG of the subject.
