Publication number: 20210267527Abstract: In situations in which an implantable medical device (e.g., a subcutaneous ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the subcutaneous ICD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the ICD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the ICD includes a first pace pulse detector configured to obtain a sensed electrical signal and analyze the sensed electrical signal to detect a first type of pulses having a first set of characteristics and a second pace pulse detector configured to obtain the sensed electrical signal and analyze the sensed electrical signal to detect a second type of pulses having a second set of characteristics.Type: ApplicationFiled: May 14, 2021Publication date: September 2, 2021Inventors: James D. REINKE, Xusheng ZHANG, Vinod SHARMA, Vladimir P. NIKOLSKI, Michael B. TERRY, Scott A. HARELAND, Daniel L. HANSEN, Donna M. SALMI

Patent number: 10448855Abstract: In situations in which an implantable medical device (IMD) (e.g., an extravascular ICD) is co-implanted with a leadless pacing device (LPD), it may be important that the IMD knows when the LPD is delivering pacing, such as anti-tachycardia pacing (ATP). Techniques are described herein for detecting, with the IMD and based on the sensed electrical signal, pacing pulses and adjusting operation to account for the detected pulses, e.g., blanking the sensed electrical signal or modifying a tachyarrhythmia detection algorithm. In one example, the IMD includes a pace pulse detector that detects, based on the processing of sensed electrical signals, delivery of a pacing pulse from a second implantable medical device and blank, based on the detection of the pacing pulse, the sensed electrical signal to remove the pacing pulse from the sensed electrical signal.Type: GrantFiled: April 15, 2015Date of Patent: October 22, 2019Assignee: Medtronic, Inc.Inventors: James D. Reinke, Xusheng Zhang, Vinod Sharma, Vladimir P. Nikolski, Michael B. Terry, Scott A. Hareland, Daniel L. Hansen, Donna M. Salmi

Patent number: 10226630Abstract: Various techniques for measuring cardiac cycle length and pressure metrics based on pulmonary artery pressures are described. One example method described includes identifying a point within a derivative signal of a cardiovascular pressure signal without reference to electrical activity of a heart, initiating a time window from the identified point in the derivative signal, identifying a point within the cardiovascular signal within the time window, and determining at least one of a systolic pressure or diastolic pressure based on the identified point.Type: GrantFiled: January 25, 2016Date of Patent: March 12, 2019Assignee: Medtronic, Inc.Inventors: Saul E Greenhut, Robert T Taepke, David R Bloem, Yong K Cho, Donna M Salmi
