  • Patent number: 11207529
    Abstract: The present disclosure relates generally to pacing of cardiac tissue, and more particularly to adjusting delivery of His bundle or bundle branch pacing in a cardiac pacing system to achieve synchronized ventricular activation. Bundle pacing may be delivered in response to determining whether the QRS parameter or activation interval is greater than a threshold. A set of AV delays may be generated, and an optimal AV delay may be selected from the stored set of AV delays. His-bundle or bundle-branch pacing may be selectively delivered based on RV or LV activation time. Pacing may also be adjusted based on dyssynchrony detected or the type of bundle branch block pattern detected.

  • Patent number: 10595813
    Abstract: A medical device system and associated method discriminate respiratory and cardiac conditions using respiratory sounds. A sensing module acquires a first signal and a second signal, at least the second signal acquired from an acoustic transducer. A processor is configured to receive the first signal and to control the sensing module to acquire the second acoustic signal in response to a change in the first signal. The processor discriminates between a cardiac condition and a respiratory condition as a cause of the change in the first signal in response to the second acoustic signal.

  • Publication number: 20200069245
    Abstract: In some examples, processing circuitry of a medical device system determines, for each of a plurality of patient parameters, a difference metric for a current period based on a value of a patient parameter determined for the current period and a value of the patient parameter determined for an immediately preceding period, and determines a score for the current period based on a sum of the difference metrics for at least some of the plurality of patient parameters. The processing circuitry determines a threshold for the current period based on scores determined for N periods that precede the current period, compares the score for the current period to the threshold, and determines whether to generate an alert indicating that an acute cardiac event of the patient, e.g., ventricular tachyarrhythmia, is predicted, and/or deliver a therapy configured to prevent the acute cardiac event, based on the comparison.

A leadless pacing device (LPD) may include a plurality of electrodes comprising a bundle pacing electrode leadlessly connected to the housing, which may be implanted proximate to or in the His bundle or bundle branch of the patient's heart. An electrical pulse generator may generate and deliver electrical His-bundle or bundle-branch stimulation pulses using the bundle pacing electrode based on sensing one or both of an atrial event and a ventricular event. The LPD may receive communication from another implantable device, such as a subcutaneously implanted device, and deliver His-bundle or bundle-branch pacing in response to the communication.
