Abstract: An ambulatory medical device includes a multi-axis posture sensor and processing circuitry. The multi-axis posture sensor is configured to provide an electrical posture sensor output representative of alignment of respective first, second, and third non-parallel axes of the ambulatory medical device with the gravitational field of the earth. The processing circuitry is configured to determine that the subject avoids lying on their left side using the posture sensor output, and compute a metric predictive of one or both of orthopnea and trepopnea in response to determining that the subject avoids lying on their left side.

Abstract: Systems and methods for detecting and managing heart failure are discussed. A medical-device system receives heart sound information sensed from the patient, generates a heart sound metric using the received heart sound information, and generate a heart failure indicator indicating whether the patient has a heart failure with preserved ejection fraction (HFpEF) or a heart failure with reduced ejection fraction (HFrEF) based at least in part on the heart sound metric. The medical-device system can detect a transition from HFpEF to HFrEF. A therapy circuit can deliver or adjust a heart failure therapy in response to the detected transition from HFpEF to HFrEF.

Abstract: Systems and methods for monitoring and managing aortic stenosis are disclosed. An exemplary medical-device system comprises a data receiver to receive heart sound information sensed by ambulatory heart sound sensors, and a stenosis detector to detect a change in aortic valve surface area from a baseline stenosis-free state using heart sound components such as S1 and S2 sounds. Based on the change in aortic valve surface area, the stenosis detector can generate an aortic stenosis indicator indicating a presence and severity of aortic stenosis. Such indicator can be provided to a user, trigger symptom monitoring and evaluation of functional deterioration in the patient, facilitate assessment of patient candidacy for aortic valve replacement, or triage heart failure management strategies.

Abstract: Systems and methods are disclosed to determine a P wave window for a patient using cardiac acceleration information of the patient, including a determined time of an S4 heart sound. Correlations between an S4 template and cardiac acceleration information in an S4 window having a duration longer than the S4 template can be determined. An S4 centroid can be determined as a peak of the determined multiple correlations, and the P wave window can be determined using the determined S4 centroid and an electromechanics delay.

Abstract: Systems, devices, and methods for monitoring and assessing blood glucose level in a patient are discussed. An exemplary system receives physiologic information from a patient using an ambulatory medical device. The physiologic information is correlated to, and different from, a direct glucose level measurement. The system determines a glucose index indicative of an abnormal blood glucose level using the received physiologic information by the two or more physiologic sensors. The system may use the glucose index to initiate or adjust a therapy, or to trigger a glucose sensor, separate from the two or more physiologic sensors, to directly measure blood glucose concentration.

Abstract: Systems and methods for detecting heart sound information from a subject's head are described. A system embodiment includes a headgear to be worn on the subject's head, and first and second sensors to sense respectively first and second physiologic signals each representing vibration, motion, or displacement conducted through patient body tissue. The sensed physiologic signals contain heart sound information. At least one of the first or the second sensor is included in the headgear, and placed at a head location to sense a physiologic signal indicative of heart sounds. The system includes a processor to generate a composite signal using the sensed first and second physiologic signals. The system may generate a heart sound metric using the composite signal, and detect a cardiac event such as an arrhythmia or worsening heart failure.

Abstract: A system and method for communication between an IMD and an external reader includes bringing a portion of a patient's body into contact with a device-body contact surface of an external reader. The reader transmits a first transdermal carrier wave from the contact surface into the patient's body, where the first carrier wave includes a request for communication with the IMD. The transdermal carrier waves are electrical conductive waves, optical waves, or acoustic waves. Upon detection of the first carrier wave, the IMD transmits a second transdermal carrier wave including a request for an access key from the reader and the reader replies by transmitting a third transdermal carrier wave including the access key back to the IMD. If the access key is valid, the IMD transmits information by radio frequency (RF) in an RF communication mode or a fourth transdermal carrier wave including data from the IMD.

Abstract: Systems and methods for detecting cardiac arrhythmia are discussed. An exemplary medical-device system includes an arrhythmia detector circuit that receives physiologic information, including respiration and heart beat information a patient, and determines whether a respiratory sinus arrhythmia (RSA) is present or absent using the respiration and the heart beat information. An indication of the presence or absence of RSA may be stored in a memory. The arrhythmia detector circuit can detect an AT episode using the indication of RSA.
