摘要： A cardiac pacemaker having an automatic pulse rate response gain factor responsive to at least one cardiac-related physiological characteristic of a patient. The pacemaker includes a rate controller that comprises a detector for detecting a plurality of individual measurements of at least one physiological characteristic over each of a plurality of pre-determined time periods, with each of the individual measurements being an average of values detected over each of a respective multiple number of incremental time periods occurring within each of the pre-determined time periods. The pacemaker saves the highest measurement from one incremental time period of each of several consecutive pre-determined time periods, and these highest measurements are averaged. Thereafter, the rate controller adjusts the rate response gain factor or slope of the pulse rate in relation to the physiological characteristic measurement and a pre-determined target pulse rate. In a preferred embodiment, two physiological characteristics are measured, with high values averaged of only one characteristic when that characteristic exceeds a threshold level of the other characteristic. One embodiment is pulse rate responsive to minute volume measurement in combination with accelerometer measurement, with accelerometer measurement requiring a threshold value over an increment of time prior to minute volume recordation for input toward rate response gain factor.

摘要： A rate adaptive cardiac rhythm management device in which the pacing rate is adjusted in accordance with changes in the patient's minute ventilation. An adaptive four-pole elliptic digital filter, preferably implemented in software, functions to attenuate any signal components due to cardiac activity and motion from the minute ventilation signal over the range of breathing frequencies encountered in going from a sedentary state to active exercise. The pacemaker incorporates a microprocessor-based controller that is programmed to compute from peak-to-peak excursions of the sensed parameter the instantaneous tidal volume. Likewise, it computes, using a zero-crossing technique, the breathing interval. Knowing the breathing interval and the instantaneous tidal volume, it is possible to compute minute ventilation over a predetermined time interval and it is that factor that is employed in developing the ultimate control signal used to vary the stimulating rate between a lower rate limit and an upper rate limit.

摘要： A cardiac pacer of the type having an implantable pulse generator and electrical leads deployed in the right ventricular chamber of the heart. The lead has a stimulating electrode as well as a plurality of sensing electrodes coupled to the pulse generator. Certain control circuitry associated with the implantable pacer provides for measurement of the impedance variations occasioned by the pumping action of the heart and a differentiating circuit operatively coupled to the impedance sensing circuit for developing a control signal corresponding to the rate of change of the impedance with respect to time. This control signal may be coupled to the timing circuit of the implantable pulse generator, allowing the pacing rate to be altered in accordance with the level of physiologic activity of the person in whom the pacer is implanted.

摘要： A multi-pole pacing/sensing lead is used to measure the instantaneous impedance in the right ventricle of a patient's heart. The resulting impedance waveform is signal processed to obtain a measure of the time interval beginning with the occurrence of a paced beat or a spontaneous QRS complex (systole marker) and ending with the point where the impedance versus time signal crosses the zero axis in the positive direction following the paced or spontaneous QRS complex initiating the interval or some other predetermined point along the positive-going waveform. The resulting time interval is inversely proportional to the contractility of the heart and is found to decrease with exercise and the introduction of catecholamines. Thus, it can be used as a control parameter for a demand-type cardiac pacemaker. A means for obviating changes in pacing rate due to long-term drift in the impedance sensing circuitry is also disclosed.
