Abstract: A system for performing a therapeutic and/or diagnostic function in a patient includes an implantable medical device configured for implantation in a patient, the implantable medical device including a motion sensor for sensing a motion signal indicative of a motion of the patient. A processing arrangement for processing the motion signal obtained by the motion sensor is configured to process said motion signal by comparing information derived from said motion signal to a defined signature motion pattern in order to identify a myocardial infarction event.

Abstract: A system of communicatively coupled nodes including at least two nodes. A first node of the at least two nodes includes a first sensor implantable and/or attachable to a patient for sensing the patient. A second node of the at least two nodes includes a second sensor for sensing the patient or a stimulator for stimulating the patient. The system is configured such that an event determined at the first node initiates an action at the second node.

A processing arrangement is configured to use a first setting of at least one detection parameter for detecting a cardiac arrhythmia event based on said electrocardiogram signals, obtain information indicative of a myocardial infarction event, and in response to obtaining said information, adapt said at least one detection parameter to a second setting different than the first setting for detecting a cardiac arrhythmia event in a time period subsequent to obtaining said information indicative of a myocardial infarction event.

Abstract: A system for performing a therapeutic and/or diagnostic function in a patient includes an implantable medical device configured for implantation in a patient, the implantable medical device including an electrode arrangement having a multiplicity of electrode poles for sensing an electrocardiogram signal. A processing arrangement is configured to process the electrocardiogram signal to derive information from the electrocardiogram signal relating to an ST segment subsequent to an R peak of a QRS complex and prior to a T wave in a cardiac cycle and to identify a myocardial infarction event based on the information.

Abstract: An implantable medical device for sensing electrocardiogram signals includes an arrangement of electrode poles configured to sense electrocardiogram signals, and a processing module for processing electrocardiogram signals obtained by the arrangement of electrode poles. The processing module is configured to identify a contraction event based on said electrocardiogram signals, classify said contraction event as an ectopic event based on a relation to other contraction events prior and/or subsequent to said contraction event, and store a snapshot representing data of said electrocardiogram signals in a time period encompassing said contraction event classified as an ectopic event.

Abstract: An implantable medical system includes an implantable medical lead including at least one electrode and an implantable medical device (IMD) coupled to the implantable medical lead. The IMD includes a sensing module that obtains electrical signals on the implantable medical lead. The electrical signals on the implantable medical lead include cardiac signals as well as noise-induced signals. The IMD also includes a noise detection module that obtains noise signals independently of the electrical signals on the implantable medical lead. A control module of the IMD adjusts a sensing threshold of the sensing module in response to detecting the noise signals via the noise detection module. In instances in which the amplitude of the noise-induced signal on the lead is too large, the IMD may transition to a noise operating mode specifically designed to accommodate noisy environments.

Abstract: An implantable medical device (IMD) configures one or more operating parameters of the IMD based on a type of source of a disruptive energy field to which the IMD is exposed. The disruptive energy field may, in one example, include magnetic and/or radio frequency (RF) fields generated by an MRI scanner. In one aspect, the IMD may distinguish between different types of MRI scanners and select an exposure operating mode tailored to reduce the effects of the particular type of MRI scanner. In another aspect, the IMD may adjust one or more operating parameters that will be used when the IMD returns to a normal operating mode after exposure to the MRI scanner based on the type of MRI scanner to which the IMD is exposed.

Abstract: This disclosure provides a pacing technique that reduces the effect of oversensing caused by noise on pacing therapy. The IMD delivers a pacing pulse subsequent to sensing an electrical signal on the lead when the sensed electrical signal coincides with an independently detected noise signal and the sensed electrical signal occurs during a period of time of an expected intrinsic cardiac signal. The IMD may, in some instances, trigger delivery of the pacing pulse during the escape interval instead of waiting for the escape interval to expire. Pacing in accordance with the techniques of this disclosure may allow for improved therapy during an MRI procedure by decreasing the risk associated with inappropriate pacing inhibition as well as decreasing the risk associated with pacing during the vulnerable period of the cardiac cycle.
