Abstract
This paper proposes a medical information system, including a portable cardioanalyzer combined with an automated workplace of a cardiologist by the use of multi-agent technology. This system allows you to monitor the state of the heart in conditions of free activity of the patient, to identify quickly responding to critical heart conditions. Distinctive features of the proposed portable cardioanalyzer are the ability to determine the critical state of the patient's heart in real time based on patent-protected methods of non-invasive cardiac diagnosis and automatically call the ambulance service for the patient, if such a heart condition is revealed.
