Abstract: The invention provides a system and a method for obtaining from the patient's body information pertaining to the blood pressure and heart rate of a patient for the purpose of enabling a physician to monitor and prescribe treatment intended to maintain a patient's blood pressure within a predetermined range, for encouraging the patient to follow the treatment and for collecting information relating to the patient's blood pressure and heart rate. Signals are generated that represent the level of blood pressure and pulse rate of a patient in a form suitable for telephonic communication. The signals are transmitted to a remote central digital processor for storage and analysis. Data resulting from the analysis is submitted to the patient or physician. An off hook and ring detect circuit is provided preventing actuation of the system when telephonic access is unavailable.
