Patent number: 10596381Abstract: An implantable or other ambulatory medical apparatus comprises a posture sensing circuit, a physiologic sensing circuit that senses a time varying physiologic signal, and a processor circuit. The processor circuit includes a posture calculation circuit and a measurement circuit. The posture calculation circuit determines a posture of the subject using posture data obtained using the posture signal and determines when the posture of the subject is steady state. The measurement circuit derives a physiologic measurement using physiologic data extracted from the physiologic signal during at least one time period when posture is determined to be steady state and provides the physiologic measurement to at least one of a user and a process in association with the determined steady state posture.Type: GrantFiled: December 14, 2011Date of Patent: March 24, 2020Assignee: Cardiac Pacemakers, Inc.Inventors: Viktoria A. Averina, John D. Hatlestad, Abhilash Patangay, Pramodsingh Hirasingh Thakur, Yi Zhang, Kenneth C. Beck

Patent number: 10456049Abstract: An apparatus comprises plurality of sensors and a processor. Each sensor provides a sensor signal that includes physiological information and at least one sensor is implantable. The processor includes a physiological change event detection module that detects a physiological change event from a sensor signal and produces an indication of occurrence of one or more detected physiological change events, and a heart failure (HF) detection module. The HF detection module determines, using a first rule, whether the detected physiological change event indicative of a change in HF status of a subject, determines whether to override the first rule HF determination using a second rules, and declares whether the change in HF status occurred according to the first and second rules.Type: GrantFiled: February 23, 2017Date of Patent: October 29, 2019Assignee: Cardiac Pacemakers, Inc.Inventors: Yi Zhang, Jeffrey E.

Patent number: 9743889Abstract: Systems and methods for detecting a worsening of patient's heart failure condition based, at least in part, on an increasing trend in a representative rapid shallow breathing index (RSBI) value over multiple days. The RSBI value may be a minimum RSBI, and more particularly may be a minimum RSBI value determined for an afternoon portion of each of the multiple days. The minimum RSBI value measured during an afternoon portion of the day may be more sensitive to changes in a patient's respiration, particularly when a patient is expected to be more active, and thus, may more readily exhibit an increasing trend when patient's heart failure is in decline.Type: GrantFiled: August 4, 2014Date of Patent: August 29, 2017Assignee: Cardiac Pacemakers, Inc.Inventors: Yi Zhang, Viktoria A.

Publication number: 20150038866Abstract: Systems and methods for detecting a worsening of a patient's heart failure condition based, at least in part, on a declining trend in a representative tidal volume value over multiple days. The tidal volume value may be a maximum tidal volume, and more particularly, a maximum tidal volume determined for an afternoon portion of each of the multiple days or a selected portion of each of the multiple days that excludes a night portion. The maximum tidal volume during these portions of the day may be more sensitive to changes in a patient's respiration, particularly when a patient is expected to be more active, and thus, may more readily exhibit a declining trend when the patient's heart failure status is in decline.Type: ApplicationFiled: August 4, 2014Publication date: February 5, 2015Inventors: Yi Zhang, Viktoria A.
