A cardiac rhythm management system provides both a safe maximum pacing rate limit and a physiological maximum pacing rate limit. The present subject matter provides a solution to problems associated with the use of a single maximum tracking rate (MTR). In one embodiment, the present subject matter utilizes two MTRs, where the first is a normal MTR and the second is a hysteresis MTR. In one embodiment, the hysteresis MTR is set higher than the normal MTR. The hysteresis MTR functions as a maximum pacing rate limit while tracking an atrial rate until the atrial rate exceeds the hysteresis MTR limit. When the atrial rate exceeds the hysteresis MTR limit, the maximum pacing rate limit is set to the normal MTR. Once the atrial rate falls below a predetermined threshold, the maximum pacing rate limit is set to the hysteresis MTR. The predetermined threshold may be set to the normal MTR, the hysteresis MTR, or other rates. In one embodiment, changing the maximum pacing rate limit in this fashion allows for uninterrupted pacing treatment for patients, such as congestive heart failure (CHF) patients, who may display fast but physiologically normal heart rates and need cardiac resynchronization therapy (CRT) at such fast heart rates. Such a pacing treatment provides for a more rapid and natural maximum pacing rate limit for the patient, while still protecting the patient from being paced at abnormally high rates.

This invention relates to non-invasive monitoring devices, in monitoring minute movements made by the body to report the presence or absence of respiration and normal heart rate. The movements being measured are the pulsations made by the normal operation of both the heart and lungs. This is accomplished by converting the body movements into electrical signals with an adapted polymorph-piezoelectric transducer. The electrical signal that is detected is a mixed signal, a signal composed of a lower frequency (breathing contraction) and the higher frequency (heart pulse). The signals are detected by separating the body motions by an adaptive filter that has a break frequency at twice the frequency of the larger body movement signal (breathing contraction).The separate body movement signals operate with associated logic circuitry to allow each signal to be independently measured, recorded, and acted upon to determine if the individual (patient) is undergoing a life threatening experience. Such an event by either signal will trigger an audio and visual display alarm which is attached on or near the patient. The alarm event trigger is also connected to a low voltage detector circuit to indicate that the supply voltage has dropped below an acceptable level.
