Abstract: Systems and methods for monitoring heart failure status in a patient are discussed. A medical-device system receives physiological and clinical information of the patient, and classifies the patient into one of a plurality of phenotypes using the received information. The plurality of phenotypes each can be characterized by a cluster physiological, clinical, demographic, or comorbidity features in a multi-dimensional feature space. Based on the classified phenotype, a heart failure detector determines a heart failure detection setting for the patient, and detects a heart failure status in the patient using the heart failure detection setting. A therapy circuit can deliver or adjust a heart failure therapy in response to the detected heart failure status.

Abstract: Systems and methods for detecting a blockage in a patient's cardiac conduction system using heart sound information is disclosed. An exemplary medical-device system includes a data receiver circuit to receive heart sound information sensed from a patient, and a controller circuit to generate a heart sound metric or characteristic from the received heart sound information. The heart sound metric can include one indicative of a presence or absence of split S1 sound. The controller circuit can detect a bundle branch block (BBB), including to discriminate a left bundle branch block (LBBB) from a right bundle branch block (RBBB), based at least in part on the heart sound metric. The BBB indicator can be provided to a user or a process executable by the medical-device system to optimize cardiac pacing and restore cardiac synchrony.

Abstract: Systems and methods for recognizing and tracking heart sound components are disclosed. An exemplary medical-device system comprises a data receiver circuit to receive heart sound information, and a heart sound recognition circuit to generate a representative heart sound segment within a cardiac cycle, such as an ensemble average of a plurality of heart sound segments taken from multiple cardiac cycles. The heart sound recognition circuit can partition the representative heart sound segment into multiple heart sound data windows, calculate spectral entropy values respectively for each of the multiple heart sound data windows, and determine one or more heart sound components including an S2 component using the calculated spectral entropy values. A physiologic event detector can detect a cardiac event using the recognized one or more heart sound components.

Abstract: Systems and methods are disclosed to determine an indication of one of an atrial fibrillation S4 heart sound or a non-atrial fibrillation S4 heart sound for an S4 signal portion of cardiac acceleration information of a patient based on determined first and second correlations of a morphology of the S4 signal portion to atrial-fibrillation and non-atrial fibrillation S4 templates, respectively, and to determine an atrial fibrillation event of the patient using cardiac electrical information of the patient and the determined indication for the S4 signal portion.

Abstract: A medical device includes a processor, an acceleration sensor, and memory. The acceleration sensor is configured to generate acceleration data that comprises a plurality of acceleration measurements. The memory comprises instructions that when executed by the processor, cause the processor to: obtain the acceleration data from the acceleration sensor; and determine, based on the acceleration data, that the medical device has flipped.

Abstract: Systems and methods for sensing respiration from a subject are discussed. An embodiment of a respiration monitoring system may include a respiration analyzer circuit to select a physiologic signal from a plurality of signals of different types indicative of respiration, such as between first and second physiologic signals that are respectively detected using first and second detection algorithms, and to compute one or more respiration parameters using the selected signal. The system may select or adjust a respiration detection algorithm for detecting the respiration parameters. The physiologic signal, or the respiration detection algorithm, may each be selected based on a signal characteristic or a patient condition. A cardiopulmonary event may be detected using the computed respiration parameter.

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 calibrating an orientation of an implantable device in a patient is described. An exemplary system includes a calibration circuit that can receive acceleration information sensed from an implantable medical device (IMD) implanted in a patient, and receive reference acceleration information sensed from a reference device associated with the patient. The acceleration information and the reference acceleration information are acquired when the patient assumes a first posture or in a first position. The calibration circuit determines a spatial relationship between an orientation of the IMD and a reference orientation of the reference device using the received acceleration information and the received reference acceleration information, and calibrate subsequent acceleration information sensed from the IMD using the determined spatial relationship to correct for the orientation of the IMD.
