Abstract: Processing circuitry (50) of a medical system is configured to determine a ventricular activation time metric and determine, based on the ventricular activation time metric, whether ventricular capture includes left bundle branch area pacing or septal pacing. The processing circuitry (50) is further configured to modify a magnitude of the ventricular pacing in response to the ventricular capture including septal pacing.

Abstract: A medical device is configured to obtain, by processing circuitry of the medical device, at least a first electrocardiogram (ECG) signal. The processing circuitry may determine a ventricular activation time using the first ECG signal for each one of multiple pacing pulses and detect a threshold difference between a first ventricular activation time associated with a first pacing pulse of the plurality of pacing pulses and a second ventricular activation time associated with a second pacing pulse of the plurality of pacing pulses. The medical device may be further configured to display the determined ventricular activation times.

Abstract: The present disclosure relates to surrogate left ventricular activation times (110, 107, 107A) that is representative of, or correlates to, left ventricular activation times for use in determining left bundle branch (LBB) (8a) capture and LBB pacing configuration. The surrogate left ventricular activation times (110, 107, 107A) may be determined, or measured, from electrical activity monitored from one or more implanted electrodes (40, 42, 44, 46, 48, 50, 58, 61, 62, 64, 66) such as, for example, a LBB pacing electrode or an electrode located in the right ventricle (28).

Abstract: A medical device is configured to receive a conduction system pacing therapy command which may correspond to one of a first conduction system pacing therapy command or a second conduction system pacing therapy command. The medical device may determine an atrioventricular (AV) pacing interval according to a first method in response to receiving the first conduction system pacing therapy command. The medical device may determine the AV pacing interval according to a second method different than the first method in response to receiving the second conduction system pacing therapy command. The medical device may schedule conduction system pacing pulses for delivery at the determined AV pacing interval.

Abstract: A therapy system includes an implantable medical device including one or more implantable electrodes (40, 42, 48, 50, 94), and a computing apparatus (24) including processing circuitry and operably coupled to the one or more implantable electrodes (40, 42, 48, 50, 94). The one or more implantable electrodes (40, 42, 48, 50, 94) include a left bundle branch (LBB) electrode positionable adjacent a portion of a patient's LBB, and a right bundle branch (RBB) electrode positionable adjacent a portion of the patient's RBB.

Abstract: An adjustable rotational connector is configured to establish electrical communication between an implantable medical lead and a cable of an external testing device while allowing rotation of the implantable medical lead relative to the cable. The coupling includes a pin that is electrically conductive. An adjustable socket is positioned within the pin and is configured to receive lead connectors of different sizes. A bearing is configured to facilitate rotation of the pin relative to the cable. An actuatable element surrounds at least a portion of the adjustable socket. The actuatable element is configured to transition between a first and second position relative to the adjustable socket to allow the adjustable socket to receive and secure the lead connector of the implantable medical lead in the adjustable socket.

Abstract: An implantable apparatus (100) and methods thereof. The implantable apparatus (100) includes a body (110) defining a distal end region (112) extending along a distal end region axis (111). The body (110) is configured to be inserted into cardiac tissue of a patient's heart at a target site. The implantable apparatus (100) also includes a plurality of markers (120) located along at least a portion of an outer surface of the distal end region (112) of the body (110). The plurality of markers (120) define a first configuration when located within the cardiac tissue and a second configuration when not located within the cardiac tissue. The first configuration is different than the second configuration.
