MULTI-SENSOR BLENDING IN A RATE RESPONSIVE CARDIAC PACEMAKER |
摘要 |
A multi-sensor blending circuit (12) for use in rate responsive cardiac pacemaker. The blending logic circuit (12) blends delta pacing rate signals from two or more sensors (22) which measure physical and physiological parameters of a patient. Programmable equations stored in the blending logic circuit (12) determine which percentages or a ratio of the delta pacing rate sensor signals comprise a single delta pacing rate signal as a function of the delta pacing rate. This delta pacing rate signal is provided to the pacing control circuitry (14) of a pacemaker. The blending ratios are dynamically determined based on the pacing rate established at the most recent cardiac cycle. The blending equations are comprised of several programmable variables, wherein the equations can be programmed by the external programmer (16) in view of clinical data.
