AMBULATORY MONITORING SYSTEM

This paper describes the Ambulatory Monitoring System (AMS) for measuring and scoring heart rate, heart rate variability, and the amount of body movement during normal daily activities. After a technical description of the system, results from a validation study are presented in which heart rate and heart rate variability measured with the AMS showed predictable variation with time of day, posture, physical activity and the type of activity that the subjects were engaged in. It is con-cluded that the Ambulatory Monitoring System is a valid system for non-invasive real-life monitoring of heart rate and heart rate variability
