    Abstract: The present disclosure pertains to cardiac pacing methods and systems, and, more particularly, to cardiac resynchronization therapy (CRT). In particular, the present disclosure pertains to determining the efficacy of CRT through use of an effective capture test (ECT). One or more embodiments comprises sensing a signal in response to a ventricular pacing stimulus. Through signal processing, a number of features are parsed from the signal. Exemplary features parsed from the signal include a maximum amplitude, a maximum time associated with the maximum amplitude, a minimum amplitude, and a minimum time associated with the minimum amplitude. The data is evaluated through use of the ECT. By employing the ECT, efficacy of CRT is easily and automatically evaluated.

    Abstract: A controller for an implantable blood pump, the implantable blood pump having an impeller. The controller includes processing circuitry configured to reduce a speed of the impeller from a set speed to a first reduced speed if a first predetermined amount of time of detected suction events occurs during a first time interval and increase the speed of the impeller from the first reduced speed if a second predetermined amount of time or less of detected suction events occur during a second time interval and a third predetermined amount of time or less of detected suction events.
