    Abstract: An implantable medical device system includes an elongated lead body carrying a hydrophone. In some embodiments, the elongated lead body has outer surface and an opening along the outer surface. The hydrophone is configured to receive acoustical signals through the opening of the lead body and generate an electrical signal representative of sounds produced at a targeted location along a patient's cardiovascular system. In some examples, the lead body outer surface has a shaped contour for directing the opening for receiving the sounds from a direction of the targeted location. A processor is enabled to receive signals from the hydrophone and detect a cardiac condition in response to the signals.

    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. A left bundle branch (LBB) cathode electrode may be implanted a left side of the septum of the patient's heart proximate to the LBB, and a right bundle branch (RBB) cathode electrode may be implanted on a right side of the septum of the patient's heart proximate to the RBB. One or both cathode electrodes may be used to deliver synchronized left and right bundle-branch pacing based on one or both of an atrial event and a ventricular event. A device for bundle branch pacing may be implanted based on determining whether an LBB block pattern or an RBB block pattern is present in monitored electrical activity.

    Abstract: An adapter configured to electrically connect a test device to an implantable medical lead comprises a rotational electrical coupling. The rotational electrical coupling is configured to electrically connect a lead electrical connector to an adapter electrical connector. The rotational electrical coupling comprises a first conductive component configured to be electrically connected to the lead electrical connector and rotatable with a proximal portion of the implantable medical lead, and a second conductive component electrically connected to the first conductive component and the adapter electrical connector. The second conductive component may be rotationally fixed. The first and second conductive components may comprise graphite or another soft metal.

    Abstract: A medical device is configured to deliver His-Purkinje pacing pulses according to multiple settings of a pacing control parameter and determine an electromechanical time delay from a ventricular electrical event to a fiducial point of the pressure signal for each of the pacing control parameter settings. The medical device may be configured to select an operating pacing control parameter from the pacing control parameter settings based on a determined electromechanical time delay being less than a threshold interval. The medical device may deliver pacing pulses to the His-Purkinje conduction system according to the selected operating pacing control parameter.

    Abstract: In some examples, a method comprises sensing one or more left-ventricular activations via one or more electrodes of a left-ventricular lead, wherein each of the one or more left-ventricular activations are in response to delivery of an electrical stimulation to a heart of a patient; determining one or more left-ventricular activation metrics based on the sensed one or more left-ventricular activations; and determining whether the electrical stimulation provided conduction system pacing based on the one or more ventricular activation metrics.
