    Abstract: In some examples, a system can be used for delivering cardiac resynchronization therapy (CRT). The system may include a pacing device configured to be implanted within a patient. The pacing device can include a plurality of electrodes, signal generation circuitry configured to deliver ventricular pacing via the plurality of electrodes, and a sensor configured to produce a signal that indicates mechanical activity of the heart. Processing circuitry can be configured to identify one or more features of a cardiac contraction within the signal, and determine whether the contraction was a fusion beat based on the one or more features.

    Abstract: The invention relates to a prosthetic valve (1) for regulating fluid flow between an upstream side (4) and a downstream side (5) and being operable between an open status and a closed status. The prosthetic valve comprises: —an orifice (2) arranged in a surrounding member (3) and extending between the upstream side (4) and the downstream side (5) wherein in the open status of the prosthetic valve (1) the fluid flow through the orifice is maximally enabled and wherein in the closed status of the prosthetic valve the fluid flow through the orifice in a restriction direction (21) from the downstream side (5) to the upstream side (4) is restricted; and —a leaflet (6) arranged in the orifice and being operable between an open status corresponding to the open status of the prosthetic valve and a closed status corresponding to the closed status of the prosthetic valve. The prosthetic valve further comprises regurgitation means (8, 15, 115, 22) arranged in the prosthetic valve for achieving regurgitation in the restriction direction and arranged for becoming ineffective after a period of deployment.

    Abstract: In some examples, determining a heart failure status using a medical device comprising one or more sensors includes determining a first value of a heart beat variability metric of a patient while an activity state of a patient satisfies an inactivity criterion based on a signal received from the one or more sensors, and determining, within a predetermined period of time after further determining that the activity state of the patient no longer satisfies the inactivity criterion, a second value of the heart beat variability metric while the activity state of the patient no longer satisfies the inactivity criterion based on the signal. A difference between the first value of the heart beat variability metric and the second value of the heart beat variability metric may be determined and the heart failure status of the patient may be determined based on the difference.

    Abstract: An implantable device and associated method for delivering multi-site pacing therapy is disclosed. The device comprises a set of electrodes including a first and second left ventricular electrodes spatially separated from one another and a right ventricular electrode, all coupled to an implantable pulse generator. The processing circuit coupled to the implantable pulse generator, the processing circuit configured to determine whether a prospective heart failure condition has occurred and if so to trigger the pulse generator to switch from a first pacing mode to a second pacing mode, the first pacing mode comprising delivering only a first pacing pulse to a left ventricle (LV) and thereafter delivering an RV pacing pulse to the right ventricular electrode within a single cardiac cycle and the second pacing mode comprising delivering first and a second pacing pulses to the LV and thereafter delivering an RV pacing pulse to the right ventricular electrode within a single cardiac cycle.
