A system and method for identifying and displaying safety alert advisories. The system of the present invention automatically performs a comparison of identification data with a safety alert advisory. The system stores identification data in a plurality of dedicated fields. Each of the dedicated fields contains information related to the patient. Upon the telemetric retrieval of the data by an external programmer, the external programmer automatically cross-correlates the data in the dedicated fields with the safety alert advisories. Upon identification of a match between the data and one of the safety alert advisories, the identified safety alert advisory is displayed to a medical practitioner. In addition, the system provides a dedicated memory to store an advisory flag. The advisory flag is marked when the programmer identifies a safety alert condition that is relevant to one of the dedicated fields. When a subsequent external programmer retrieves the data from the dedicated fields, the external programmer can notify the medical practitioner that a safety alert advisory exists even though the safety alert advisory was never directly input into the subsequent external programmer.

An antitachycardia stimulation device that automatically adjusts its detection rate threshold as a function of a sensed physiological parameter indicative of cardiac rate. The implantable antitachycardia stimulation device includes heart rate detection circuitry and antitachycardia therapy circuitry for applying a specific antitachycardia therapy in the event that the detected heart rate falls within at least one tachycardia rate zone. The tachycardia rate zone is defined by a lower threshold limit, and may also be defined by an upper threshold limit if more than one rate zone is used. The lower threshold limit is automatically adjusted as a function of an independently sensed physiological parameter that predicts a normal or natural change in the heart rate. If more then one rate zone is used, other threshold limits may also be adjusted automatically as a separate function of the same sensed physiological parameter. In one embodiment of the invention, the implantable stimulation device comprises a rate-responsive pacemaker, and the sensed physiological parameter used to adjust the rate threshold limit(s) is also used to define a sensor indicated rate signal to control the pacing rate of the pacemaker.
