Patent number: 9833624Abstract: A cardiac rhythm management system provides an increase in pacing rate as a combination of responses to three characteristics of a relative-temperature signal: a dip, a positive slope, and a positive magnitude. The relative-temperature signal is the difference between a short-term and a long-term temperature average. A dip produces a limited and temporary rate increase having a first proportionality. A positive slope produces a rate increase with a second proportionality. A positive magnitude produces a rate increase with a third proportionality. The dip response seeds the slope response to provide a seamless and immediate rate transition after a dip. The cardiac rhythm management system limits and filters the sum of the rate increases to provide a sensor indicated rate, which is used to stimulate the heart.Type: GrantFiled: May 14, 2015Date of Patent: December 5, 2017Assignee: Pacesetter, Inc.Inventors: Donald Chin, Matthew G.
