Patent Number Title Of Patent Date Issued
8290590 Dynamic morphology based atrial automatic threshold October 16, 2012
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
8271087 Methods and systems for selecting capture verification modes September 18, 2012
Methods and systems are directed to selecting from a variety of capture verification modes. A plurality of capture verification modes, including a beat by beat capture detection mode and a capture threshold testing mode without intervening beat by beat capture detection is provided. An
8271086 Pacing output determination based on selected capture threshold values September 18, 2012
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
8155741 Retrograde atrial sensing for identifying sub-threshold atrial pacing April 10, 2012
Atrial capture threshold testing is performed in accordance with an atrial capture threshold testing schedule. Monitoring for retrograde P-waves occurs at least during times other than times during which scheduled atrial capture threshold testing is performed. In response to detectin
8145296 Adaptive windowing for cardiac waveform discrimination March 27, 2012
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
7899535 Automatic electrode integrity management systems and methods March 1, 2011
This document discusses, among other things, systems and methods for automatic electrode integrity management. Interelectrode impedance is measured for various electrode combinations of an implantable cardiac function management device. The impedance data is processed, such as at an
7801610 Methods and systems for management of atrial retrograde conduction and pacemaker mediated tachya September 21, 2010
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 at
7657314 Methods and systems for selecting capture verification modes February 2, 2010
Methods and systems are directed to selecting from a variety of capture verification modes. A plurality of capture verification modes, including a beat by beat capture detection mode and a capture threshold testing mode without intervening beat by beat capture detection is provided. An
7457666 Retrograde atrial sensing for identifying sub-threshold atrial pacing November 25, 2008
Methods and systems for delivering a pacing pulse to an atrium during a cardiac cycle. A retrograde P-wave may be identified during the cardiac cycle, indicative of sub-threshold atrial pacing. Delivery of the pacing pulse to the atrium may be adjusted in a subsequent cardiac cycle in
