Adaptive Windowing For Cardiac Waveform Discrimination

View page
US Patent:
7574260, Aug 11, 2009
Filed:
Apr 28, 2005
Appl. No.:
11/116578
Inventors:
Kevin John Stalsberg - White Bear Lake MN, US
Yanting Dong - Shoreview MN, US
Scott A. Meyer - Rochester MN, US
Eric Keith Enrooth - Lino Lakes MN, US
Derek Daniel Bohn - Woodbury MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61B 5/04
A61N 1/08
US Classification:
607 28, 600509, 607 27
Abstract:
Cardiac devices and methods provide adaptation of detection windows used to determine a cardiac response to pacing. Adapting a detection window involves sensing a cardiac signal indicative of a particular type of cardiac pacing response, and detecting a feature of the sensed cardiac signal. The cardiac response detection window associated with the type of cardiac pacing response is preferentially adjusted based on the location of the detected cardiac feature. Preferential adjustment of the detection window may involve determining a direction of change between the detection window and the detected feature. The detection window may be adapted more aggressively in a more preferred direction and less aggressively in a less preferred direction.

Methods And Systems For Managing Fusion And Noise In Cardiac Pacing Response Classification

US Patent:
7765004, Jul 27, 2010
Filed:
Apr 28, 2005
Appl. No.:
11/116565
Inventors:
Kevin John Stalsberg - White Bear Lake MN, US
Yanting Dong - Shoreview MN, US
Scott A. Meyer - Rochester MN, US
John Michael Voegele - Bethel MN, US
Derek Daniel Bohn - Woodbury MN, US
Eric Keith Enrooth - Lino Lakes MN, US
Clayton Scott Foster - Andover MN, US
David William Yost - Brooklyn Park MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1/08
US Classification:
607 28
Abstract:
Methods and systems for detecting noise in cardiac pacing response classification processes involve determining that a cardiac response classification is possibly erroneous if unexpected signal content is detected. The unexpected signal content may comprise signal peaks that have polarity opposite to the polarity of peaks used to determine the cardiac response to pacing. Fusion/noise management processes include pacing at a relatively high energy level until capture is detected after a fusion, indeterminate, or possibly erroneous pacing response classification is made. The relatively high energy pacing pulses may be delivered until capture is detected or until a predetermined number of paces are delivered.

Methods And Systems For Management Of Atrial Retrograde Conduction And Pacemaker Mediated Tachyarrhythmia

US Patent:
7801610, Sep 21, 2010
Filed:
Nov 17, 2006
Appl. No.:
11/601092
Inventors:
Derek D. Bohn - Woodbury MN, US
Ankur Garg - Minneapolis MN, US
Eric K. Enrooth - Lino Lakes MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1/362
US Classification:
607 28, 607 9, 607 14, 607 27
Abstract:
Methods and systems for classifying cardiac responses to pacing stimulation and managing retrograde conduction and pacemaker mediated tachyarrhythmia are described. An atrial pacing pulse and a ventricular pacing pulse are delivered during a paced cardiac cycle. A post ventricular atrial refractory period (PVARP) is timed following the ventricular pacing pulse. The system determines if the atrial pacing pulse captures the atrium. An atrial depolarization occurring after the paced cardiac cycle is sensed. Retrograde management is initiated if the atrial pacing pulse did not capture the atrium and the atrial depolarization occurred during the PVARP. Pacemaker mediated tachyarrhythmia (PMT) is initiated if the atrial pacing pulse did not capture the atrium and the atrial depolarization did not occur during the PVARP.

Pacing Output Determination Based On Selected Capture Threshold Values

US Patent:
8271086, Sep 18, 2012
Filed:
Dec 22, 2008
Appl. No.:
12/341617
Inventors:
John Voegele - Bethel MN, US
Clayton Foster - Andover MN, US
David W. Yost - Brooklyn Park MN, US
Scott Meyer - Lakeville MN, US
Yanting Dong - Shoreview MN, US
Kevin J. Stalsberg - White Bear Lake MN, US

Eric K. Enrooth - Lino Lakes MN, US
Assignee:
Cardiac Pacemakers, Inc. - Saint Paul MN
International Classification:
A61N 1/365
A61N 1/08
US Classification:
607 28
Abstract:
Approaches for adjusting the pacing energy delivered by a pacemaker are provided. Adjusting the pacing energy involves performing a plurality of capture threshold tests, each capture threshold test measuring a capture threshold of the heart. One or more measured captured thresholds are selected, including at least one capture threshold that is higher relative to other measured capture thresholds acquired by the plurality of capture threshold tests. The pacing energy is adjusted based on the one or more selected capture thresholds.

Dynamic Morphology Based Atrial Automatic Threshold

View page
US Patent:
8290590, Oct 16, 2012
Filed:
Nov 17, 2006
Appl. No.:
11/601217
Inventors:
Derek D. Bohn - Woodbury MN, US
Ankur Garg - Minneapolis MN, US
Eric K. Enrooth - Lino Lakes MN, US
Assignee:
Cardiac Pacemakers, Inc. - Saint Paul MN
International Classification:
A61N 1/362
US Classification:
607 28
Abstract:
Methods and systems for performing capture threshold tests are described. During an initialization procedure a capture detection interval and capture detection threshold are determined based on peak values of cardiac signals sensed following the supracapture threshold initialization pulses. Following initialization, a plurality of pacing pulses to the atrium are delivered and the peak values of the cardiac signals sensed following each of the plurality of pacing pulses are determined. The peak values are compared to the pacing artifact threshold and the capture detection threshold. A timing of each of the peak values is compared to the capture detection interval. For each pacing pulse, discrimination between a captured response, a noncaptured response, and a fusion response is based on the peak value and timing comparisons.

Methods And Systems For Mitigating The Occurrence Of Arrhythmia During Atrial Pacing

US Patent:
8452405, May 28, 2013
Filed:
May 3, 2010
Appl. No.:
12/772725
Inventors:
Eric Enrooth - Lino Lakes MN, US
Yanting Dong - Shoreview MN, US
Kenneth N. Hayes - Blaine MN, US
Gary T. Seim - Minneapolis MN, US
Kevin John Stalsberg - White Bear Lake MN, US
Aaron McCabe - Minneapolis MN, US
Assignee:
Cardiac Pacemakers, Inc. - St. Paul MN
International Classification:
A61N 1/362
US Classification:
607 28, 607 9
Abstract:
Noncaptured atrial paces can result in long-short cardiac cycles which are proarrhythmic for ventricular tachyarrhythmia. Approaches are described which are directed to avoiding proarrhythmic long-short cycles. For cardiac cycles in which the atrial pace captures the atrium, a first post ventricular refractory period (PVARP) and a first A-A interval are used. For cardiac cycles in which the atrial pace does not capture the atrium, both an extended PVARP and an extended A-A interval are used. The A-A interval following a noncaptured atrial pace is extended from an atrial depolarization sensed during the extended PVARP.
