Abstract: This document discusses, among other things, systems and methods to determine an indication of contractility of a heart of a patient using received physiologic information, and to determine blood pressure information of the patient using the heart sound information and the determined indication of contractility of the heart. The system can include an assessment circuit configured to determine an indication of contractility of a heart of the patient using first heart sound (S1) information of the patient, and to determine blood pressure information of the patient using second heart sound (S2) information of the patient and the determined indication of contractility of the heart.

Abstract: An implantable medical device (IMD) with a receiving coil for wireless power transfer. The receiving coil may be disposed about a flux concentrator located in a housing of the IMD. The flux concentrator may concentrate non-radiative near-field energy through the receiving coil. In some cases, the near-field energy may be captured and converted into electrical energy that may be used to recharge a rechargeable power source of the IMD.

Abstract: Systems and methods for detecting atrial tachyarrhythmias (AT) such as atrial fibrillation (AF) are disclosed. A medical system can include a cardiac signal sensor circuit to sense a cardiac electrical signal and a heart sound (HS) sensor to sense heart a HS signal A cardiac electrical signal metric, including a cycle length variability or a detection of atrial electrical activity, can be generated from the cardiac electrical signal A HS metric can be generated from the HS signal, including a status of detection of S4 heart sound or a S4 heart sound intensity indicator. The system can include an AT detector circuit that can detect an AT event, such as an AF event, using the cardiac electrical signal metric and the HS metric The system can additionally classify the detected AT event as an AF or an atrial flutter event.

Abstract: Systems, devices, and methods for determining occurrences of myocardial infarctions are disclosed. In one embodiment, a method of sensing for an occurrence of a myocardial infarction may include sensing a baseline accelerometer signal during a baseline, determining a baseline template based on one or more characteristics of the baseline accelerometer signal, and storing the baseline template in a memory. The method may further include sensing an accelerometer signal during a test period subsequent to the baseline, determining a test template based on one or more characteristics of the accelerometer signal during the test period, and comparing the baseline template with the test template, and based on the comparison, determining if a myocardial infarction occurred in the patient's heart. If it is determined that a myocardial infarction occurred in the patient's heart, the method may further include displaying an indication on a display that a myocardial infarction occurred.

Abstract: Systems and methods for determining an abnormal glycemic event using surrogates for glucose are disclosed herein. In an embodiment, a medical system includes a medical device associated with a subject and a processor communicatively coupled to the medical device. The medical device is configured to sense a signal corresponding to a presence of a compound in at least one of: an exhalation breath, interstitial fluid, blood and urine, wherein the compound is a surrogate for glucose. The processor is configured to receive the signal corresponding to the presence of the compound; determine the presence of the compound based on the received signal; and determine the subject is experiencing an abnormal glycemic event in response to the determined presence of the compound.

Abstract: System and methods for energy adaptive communications between medical devices are disclosed. In one example, a medical device includes a communication module configured to deliver a plurality of pulses to tissue of a patient, where each pulse has an amount of energy. A control module operatively coupled to the communication module, may be configured to, for each delivered pulse, determine whether the delivered pulse produces an unwanted stimulation of the patient and to change the amount of energy of the plurality of pulses over time so as to identify an amount of energy that corresponds to an unwanted stimulation threshold for the pulses. The control module may then set a maximum energy value for communication pulses that is below the unwanted stimulation threshold, and may deliver communication pulses below the maximum energy value during communication with another medical device.
