Abstract: Method and systems control a rotational speed of a blood pump during ventricular diastole. A method includes controlling a blood pump in accordance with a first segment operational mode. A controller monitors the blood flow rate through the blood pump. The controller determines, based on the blood flow rate, whether continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than a target minimum blood flow rate. In response to a determination that continued controlling of the blood pump per the first segment operational mode would result in the blood flow rate through the blood pump being less than the target minimum blood flow rate, the controller controls the rotational speed of the blood pump so that the blood flow rate through the blood pump is approximate to the target minimum blood flow rate.

Abstract: Apparatus includes a flexible intraventricular receptacle that assumes a first volume upon passage of fluid that is not blood into the receptacle and a second, smaller volume upon passage of the fluid out of the receptacle. An expandable extracardiac receptacle expands upon transfer of the fluid into the extracardiac receptacle from the intraventricular receptacle and contracts upon passage of the fluid out of the extracardiac receptacle. A transmyocardial conduit allows passage of the fluid between the intraventricular receptacle and the extracardiac receptacle responsively to a cardiac cycle. During ventricular systole, a volume of fluid is expelled from the intraventricular receptacle, through the conduit, and into the extracardiac receptacle, producing a corresponding decrease in a total volume of the ventricle during isovolumetric contraction of the ventricle. Other embodiments are also described.

According to an embodiment, one or more physiological variables are longitudinally measured; resting heart rate is measured from which a timeseries is constructed; outlier anomalous values are removed from the timeseries, it is de-trended and/or de-meaned; and a serial normal sinus rhythm beats (SDNN) and/or other parameters are determined.
