  • Publication number: 20220111215
    Abstract: Systems and methods for monitoring and treating patients with heart failure are discussed. The system can store in a memory stimulation parameters, including stimulation timing parameters for a plurality of heart rate ranges. The system includes a plurality of timers with respective durations for the plurality of heart rate ranges. A stimulation control circuit can identify a target heart range in which a detected heart rate falls, and measure an atrioventricular (AV) conduction characteristic value in response to the timer for the target heart range being expired at the detected heart rate. The stimulation control circuit can update a stimulation parameter corresponding to the target heart rate range using the measured AV conduction characteristic. The updated stimulation parameter can be used in cardiac stimulation.

  • Patent number: 11185700
    Abstract: Systems and methods for monitoring and treating patients with heart failure (HF) are discussed. The system may sense cardiac signals, and receives information about patient physiological or functional conditions. A stimulation parameter table that includes recommended values of atrioventricular delay (AVD) or other timing parameters maybe created at a multitude of patient physiological or functional conditions. The system may periodically reassess patient physiological or functional conditions. A therapy programmer circuit may dynamically switch between left ventricular-only pacing and biventricular pacing, or switch between single site pacing and multisite pacing based on the patient condition. The therapy programmer circuit may adjust AVD and other timing parameters using the cardiac signal input and the stored stimulation parameter table. A HF therapy may be delivered according to the determined stimulation site, stimulation mode, and the stimulation timing.

  • Patent number: 10646131
    Abstract: An apparatus includes a cardiac signal sensing circuit configured to generate a sensed cardiac signal representative of electrical cardiac activity of a subject, a buffer memory and a pause detection circuit. The pause detection circuit is configured to: identify ventricular depolarization in the cardiac signal or the sampled cardiac signal; detect a candidate pause episode using the cardiac signal in which delay in ventricular depolarization exceeds a specified delay threshold; identify noise events in a stored cardiac signal; and discard the cardiac signal of the candidate pause episode when a number of noise events satisfies a specified noise event number threshold, otherwise store the cardiac signal of the candidate pause episode as a bradycardia pause episode.

  • Patent number: 10314502
    Abstract: Systems and methods for evaluating multiple candidate sensing vectors for use in sensing electrical activity of a heart are disclosed. The system can sense physiologic signals using each of a plurality of candidate sensing vectors, and generate respective signal intensity indicators and interference indicators using the physiologic signals sensed by using the respective sensing vectors. The system can also receive electrode information of each of the candidate sensing vectors, including information about sensing electrodes that are also used for delivering cardiac electrostimulation. The system can rank at least some of the plurality of candidate sensing vectors according to the signal intensity indicators, the interference indicators, and the electrode information. The system can also include a user interface for displaying the ranked sensing vectors, and allowing the user to select at least one sensing vector for use in sensing the cardiac electrical activity.
