A system comprises processing circuitry and memory comprising program instructions that, when executed by the processing circuitry, cause the processing circuitry to: apply a first set of rules to first patient parameter data for a first determination of whether sudden cardiac arrest of a patient is detected; determine that a one or more context criteria of the first determination are satisfied; and in response to satisfaction of the context criteria, apply a second set of rules to second patient parameter data for a second determination of whether sudden cardiac arrest of the patient is detected. At least the second set of rules comprises a machine learning model, and the second patient parameter data comprises at least one patient parameter that is not included in the first patient parameter data.

Acute health event monitoring

An example device of a patient includes an antenna configured to wirelessly receive communication from a medical device; and processing circuitry coupled to the antenna and configured to: determine that the received communication indicates that a patient is experiencing an acute health event; in response to the determination, determine one or more physical states of the patient based on sensed data from one or more sensors; confirm that the patient is not experiencing the acute health event based on the determined one or more physical states; and output information based on the confirmation that the patient is not experiencing the acute health event.

Automatic alert control for acute health event

In some examples, an electromechanical disassociation state (EMD) of a heart of a patient can be treated by delivering electrical stimulation to a tissue site to at least one of modulate afferent nerve activity or inhibit efferent nerve activity upon determining that the heart is in an electromechanical dissociation state, where the tissue site comprises at least one of a nonmyocardial tissue site or a nonvascular cardiac tissue site. The delivery of electrical stimulation may effectively treat the EMD state of the heart, e.g., by enabling effective mechanical contraction of the heart. In another example, an electromechanical disassociation state of a heart of a patient can be treated by determining autonomic nervous system activity associated with a detected EMD state of the heart of a patient, and delivering electrical stimulation therapy to the patient based on the determined autonomic nervous system activity of the patient associated with the EMD state.

Detecting and treating electromechanical dissociation of the heart

Electrical crosstalk between two implantable medical devices or two different therapy modules of a common implantable medical device may be evaluated, and, in some examples, mitigated. In some examples, one of the implantable medical devices or therapy modules delivers electrical stimulation to a nonmyocardial tissue site or a nonvascular cardiac tissue site, and the other implantable medical device or therapy module delivers cardiac rhythm management therapy to a heart of the patient.

Implantable medical device crosstalk evaluation and mitigation

A system including a programmable implantable monitoring device and a programmer for programming the device and a method of use thereof. The programmer may be configured to transmit programming commands responsive to entry of a reason for monitoring to the implantable device including a prioritization of an arrhythmia storage criterion. The implantable may be configured to thereafter store and/or transmit records of the arrhythmia according to the prioritization. The programmer may be configured to transmit the patient's age to the implantable device and the implantable may be configured to thereafter apply arrhythmia detection criteria based upon the patient's age.

Method and apparatus for automatic configuration of implantable medical devices

An electrical parameter value indicative of an impedance of an electrical path between a first medical device implanted within a patient and a second medical device implanted within the patient may be determined by generating and delivering an electrical signal between electrodes connected to the first medical device and sensing the electrical signal with two or more sense electrodes connected to the second medical device. In some examples, the electrical parameter value indicative of the impedance may be used to detect a system integrity issue, such as relative movement between the first and second medical devices, such as between leads connected to the medical devices, or a lead-related condition. In other examples, the determined impedance may indicate a transthoracic impedance of the patient.

Interdevice impedance

Techniques for minimizing interference between the first and second medical devices or between the different therapy modules of a common medical device are described herein. In some examples, a medical device may include shunt-current mitigation circuitry and/or at least one clamping structure that helps minimize or even eliminate shunt-current that feeds into a first therapy module of the medical device via one or more electrodes electrically connected to the first therapy module. The shunt-current may be generated by the delivery of electrical stimulation by a second therapy module. The second therapy module may be enclosed in a common housing with the first therapy module or may be separate, e.g., a part of a separate medical device.

Shunt-current reduction techniques for an implantable therapy system

An implantable medical system that includes a cardiac therapy module and a neurostimulation therapy module may identify when neurostimulation electrodes have migrated toward a patient's heart. In some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on a physiological response to an electrical signal delivered to the patient via the neurostimulation electrodes. In addition, in some examples, the system may determine whether the neurostimulation electrodes have migrated toward the patient's heart based on an electrical cardiac signal sensed via the neurostimulation electrodes.

Therapy system including cardiac rhythm therapy and neurostimulation capabilities

An implantable medical device (IMD) may include a battery dedicated to providing cardiac stimulation therapy and a separate power source that provides power for electrical stimulation therapy. Such a configuration preserves the battery dedicated for providing cardiac stimulation therapy even if the second power source is depleted. As an example, the IMD may comprise a cardiac stimulation module configured to deliver at least one stimulation therapy selected from a group consisting of pacing, cardioversion and defibrillation. The IMD further comprises a electrical stimulation module configured to deliver electrical stimulation therapy, a first power source including a battery, wherein the first power source is configured to supply power to the cardiac stimulation module and not to the electrical stimulation module, and a second power source. The second power source is configured to supply power to at least the electrical stimulation module.

Implantable medical device including two power sources

An implantable medical system is disclosed that is configured to detect a laryngeal activation response of a patient to an electrical stimulation signal. Detection of the laryngeal activation can be used to control vagal stimulation therapy to a patient.

An implantable medical device and associated method store physiological data in response to detecting a physiological event. The medical device includes multiple first memory locations allocated to each of a number of physiological event types and a second single memory location allocated for storing entries of physiological signal data corresponding to each of the plurality of physiological event types.
