  • Publication number: 20240189603
    Abstract: Methods, devices, and program products are provided under control of one or more processors within an implantable medical device (IMD) that senses far field (FF) signals between a combination of electrodes coupled to the IMD. Correlation scores are determined by comparing the FF signals associated with a number of beats to a template. The correlation scores of the number of beats are compared to a correlation threshold, and correlation variability scores are determined for the number of beats. Shock delivery, by a pulse generator within the IMD, is postponed in response to i) a first number of beats within the number of beats having the correlation scores that are less than the correlation threshold, and ii) a second number of beats within the number of beats having correlation variability scores that are less than a correlation variability threshold.

  • Patent number: 11701051
    Abstract: Systems and methods for detecting arrhythmias in cardiac activity are provided and include memory to store specific executable instructions. One or more processors are configured to execute the specific executable instructions for obtaining first and second far field cardiac activity (CA) data sets over primary and secondary sensing channels, respectively, in connection with a series of beats. The system detects candidate atrial features from the second CA data set, identifies ventricular features from the first CA data set and utilizes the ventricular features to separate beat segments within the second CA data set. The system automatically iteratively analyzes the beat segments by overlaying an atrial activity search window with the second CA data set and determines whether one or more of the candidate atrial features occur within the atrial activity search window.

  • Publication number: 20230148938
    Abstract: Computer implemented methods and implantable medical devices (IMD) are provided that obtain cardiac activity (CA) signals for a cardiac beat and compare the CA signals to a sensitivity level to detect a sensed event. One or more processors are configured to change the sensitivity level, utilized by the sensing circuitry, over the cardiac beat based on an adaptive sensitivity profile. The adaptive sensitivity profile has a maximum sensitivity limit (MSL). The process determines whether a characteristic of interest (COI) from a candidate event satisfies criteria relative to the COI for a collection of prior sensed events, declares the candidate event to be a valid sensed event or a false sensed event based on the determine operation; and adjusts the maximum sensitivity limit based on when the COI from the candidate event satisfies the criteria to provide adaptive sensing of CA signals.

  • Patent number: 11633141
    Abstract: Computer implemented methods and systems for detecting arrhythmias in cardiac activity are provided. The method is under control of one or more processors configured with specific executable instructions. The method obtains a far field cardiac activity (CA) data set that includes far field CA signals for beats. The method applies a feature enhancement function to the CA signals to form an enhanced feature in the CA data set. The method calculates an adaptive sensitivity level and sensitivity limit based on the enhanced feature from one or more beats within the CA data set and automatically iteratively analyzes a beat segment of interest by comparing the beat segment of interest to the current sensitivity level to determine whether one or more R-waves are present within the beat segment of interest.

  • Publication number: 20230121674
    Abstract: Described herein are implantable medical devices and systems, and methods for use therewith, for reducing T-wave oversensing and arrythmia undersensing that occur due to inappropriate filtering of a signal indicative of cardiac electrical activity. A method includes obtaining a signal indicative of cardiac electrical activity, and using a first bandpass filter to produce a first filtered version thereof, using a second bandpass filter to produce a second filtered version thereof, wherein the first bandpass filter passes frequencies within a first frequency range, and the second bandpass filter passes frequencies within a second frequency range that is wider than the first frequency range. The method also includes selectively changing from using the first filtered version of the signal to monitor for a VS event, to using the second filtered version of the signal to monitor for a VS event, based on first criteria, and vice versa, based on second criteria.

  • Publication number: 20230072043
    Abstract: Described herein are methods, devices, and systems that identify ventricular sensed (VS) events from a signal indicative of cardiac electrical activity, such a far-field EGM or ECG signal, and monitor for an arrythmia and/or perform arrythmia discrimination based on the VS events. Beneficially, such embodiments reduce the probability of double-counting of R-wave, or more generally, of oversensing VS events, and thereby provide for improved arrythmia detection and arrythmia discrimination.

  • Patent number: 11547339
    Abstract: A computer implemented method and system for detecting arrhythmias in cardiac activity are provided. The method is under control of one or more processors configured with specific executable instructions. The method obtains far field cardiac activity (CA) signals and applies a direction related responsiveness (DRR) filter to the CA signals to produce DRR filtered signals. The method compares a current sample from the CA signals to a prior sample from the DRR filtered signals to identify a direction characteristic of the CA signals and defines the DRR filter based on a timing constant that is set based on the direction characteristic identified. The method analyzes the CA signals in connection with the DRR filtered signals to identify a peak characteristic of the CA signals and determines peak to peak intervals between successive peak characteristic. The method detects at least one of noise or an arrhythmia based on the peak to peak intervals and records results of the detecting.
