摘要： A leadless cardiac pacemaker (LCP) may include a three-axis accelerometer. Acceleration signals from each of the three axes of the accelerometer may be combined into a combined acceleration signal and a predetermined morphological feature may be identified in a magnitude of the combined acceleration signal. The relative timing of the predetermined morphological signal relative to the cardiac cycle duration may be used to ascertain whether a detected arrhythmia is an arrhythmia that should be treated by the LCP or should not be treated by the LCP.

摘要： Methods and systems in which a first medical device provides patient status details to a second medical device. Patient status details may include one or more of patient posture and/or patient activity level, or other indications of patient status. The second medical device, in response to information about patient status and changes in patient status, uses a sensing configuration management function to respond to and accommodate the change in patient status. In an example, a first medical device monitors patient posture and communicates information related to patient posture to a second medical device, which then tailors sensing configurations to the patient posture.

摘要： Methods and systems for use of the Q-wave to R-wave interval to guide placement of a leadless cardiac pacemaker are disclosed. An implant delivery device is equipped with sensing electrodes to sense R-wave onset in a ventricle of a patient's heart to allow placement at a location of last or latest onset of the R-wave. Guidance tools are provided to assist in determination of the Q-wave to R-wave interval during implantation. For a chronic system, a cooperative approach is disclosed in which an implantable medical device and a leadless cardiac pacemaker exchange data to determine Q-wave to R-wave intervals and enhance cardiac resynchronization therapy delivery by the leadless cardiac pacemaker.
