Apr 20, 2004

Appl. No.:

10/828883

Inventors:

Michael Paris - San Francisco CA, US

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61B 5/04

US Classification:

600519, 600509, 607 17, 607 18, 607 19

Abstract:

A device, such as an implantable cardiac device, and methods for determining exercise diagnostic parameters of a patient are disclosed. Specifically, a maximum observed heart rate of a patient during exercise can be identified when an activity level and a heart rate measurement of the patient exceed predetermined thresholds. Included are methods for filtering out premature heartbeats or noise from the maximum heart rate determination. Methods of determining other exercise parameters, such as workload are also disclosed. The device includes hardware and/or software for performing the described methods.

Appl. No.:

10/828897

Inventors:

Michael Paris - San Francisco CA, US

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61B 5/04

US Classification:

600519, 600509

Abstract:

A device, such as an implantable cardiac device, and methods for determining heart rate recovery of a patient after exercise. Specifically, the method includes identifying a first heart rate indicative of exercise, a second heart rate indicative of a slow-down in exercise, and using the first and second heart rates to determine a measure of heart rate recovery. The first heart rate may be identified when a heart rate measurement and/or an activity level exceeds a predetermined threshold. The second heart rate may be identified based when a heart rate measurement and/or the activity level falls below a predetermined threshold. The device includes hardware and/or software for performing the described methods.

Filed:

May 2, 2005

Appl. No.:

11/120459

Inventors:

Michael Paris - San Francisco CA, US
Eric Husky - Mountain View CA, US

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61N 1/365

US Classification:

607 18, 607 9, 607 15

Abstract:

An implantable cardiac stimulation device provides bichamber pacing and dynamic bichamber and single chamber sensing. The device includes a sensing circuit that senses activity of a heart, a lead system coupled to a plurality of chambers of the heart, and a cardiac rate circuit that determines a cardiac rate of the heart. A control circuit causes the lead system to couple the sensing circuit to corresponding chambers of the heart to enable bichamber trigger pacing when the cardiac rate is below a given rate and to a single chamber of the heart when the cardiac rate is above the given rate to enable enhanced tachycardia sensing.

Appl. No.:

11/405129

Inventors:

Cecilia Xi - Sunnyvale CA, US
Michael Paris - San Francisco CA, US

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61B 5/04

US Classification:

600519, 600509

Abstract:

One or more sensors sense patient heart rate and patient activity and provide related signals to a processor. The processor is responsive to sensor signals and obtains an activity threshold based on historical patient heart-rate signals and historical patient activity signals. The processor periodically derives a correlation value from current patient heart-rate signals and current patient activity signals and compares the correlation values to the activity threshold. A start of activity is noted when a correlation value exceeds the activity threshold; while an end of activity is noted when a correlation value fails to exceed the activity threshold. Activity is identified as exercise when correlation values continue to exceed the activity threshold for a predetermine amount of time, while an end of exercise is noted when correlation values fall below the activity threshold for a predetermined amount of time.

Assignee:

Pacesetter, Inc. - Sunnyvale CA

International Classification:

A61B 5/04

US Classification:

600509

Abstract:

Implantable systems, and methods for use therein, for monitoring for mitral valve regurgitation (MR) are provided. An electrogram (EGM) signal and a corresponding pressure signal are obtained, where the EGM signal is representative of electrical functioning of the patient's heart during a plurality of cardiac cycles, and the corresponding pressure signal is representative of pressure within the left atrium the patient's heart during the cardiac cycles. Windows of the pressure signal are defined, based on events detected in the EGM signal, and measurements from the windows are used to monitor for MR.
