Abstract: 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.

Abstract: A medical device is configured to produce an accelerometer signal and detect a patient fall from the accelerometer signal. The device generates a body posture signal and a body acceleration signal from the accelerometer signal and detects a patient fall in response to determining that the body posture signal and the body acceleration signal meet fall detection criteria. The medical device is configured to receive a truth signal from another device that is not the medical device. The truth signal may indicate that the detected patient fall is a falsely detected patient fall and, responsive to receiving the truth signal, the medical device adjusts at least one fall detection control parameter.

Abstract: An implantable medical device system includes a pacemaker and an extravascular implantable cardioverter defibrillator (ICD). The pacemaker is configured to acquire a cardiac electrical signal, determine RR intervals from the cardiac electrical signal, apply ventricular tachycardia detection criteria solely to the RR intervals, detect ventricular tachycardia (VT) when the detection criteria are met; and deliver anti-tachycardia pacing in response to detecting the VT before the extravascular ICD delivers a shock therapy.

Abstract: An implantable medical device comprises a sensing module configured to obtain electrical signals from one or more electrodes and a control module configured to process the electrical signals from the sensing module in accordance with a tachyarrhythmia detection algorithm to monitor for a tachyarrhythmia. The control module detects initiation of a pacing train delivered by a second implantable medical device, determines a type of the detected pacing train, and modifies the tachyarrhythmia detection algorithm based on the type of the detected pacing train.

Abstract: A medical device is configured to obtain impedance measurements from each one of multiple impedance measurement electrode vectors and determine an estimate of impedance of body tissue or a body cavity, e.g., a thoracic impedance estimate, by computing an impedance of a circuit model of impedance using the multiple impedance measurements. The medical device may be configured to determine that the impedance estimate meets fluid condition detection criteria and detect a fluid status condition in response to the impedance estimate meeting the fluid condition detection criteria.
