A cardiac state system, comprising a processing unit (4) configured to receive input signals (6) including parameters from, or related to, one or many registration points or areas within or outside a heart (8), and a storage unit (10) where one or many search tools are stored. The processing unit (4) is configured to process the input signals (6), by applying said search tools, to identify point of interests (POI), being landmarks, patterns and/or group patterns. The processing unit (4) is further configured to search for and identify global and/or regional event markers among said POIs to evaluate hydro-mechanical and/or hydro-dynamic functions of the heart. Preferably, at least some of said identified event markers are associated to the AV-piston defined according to the dynamic adaptive piston pump (DAPP) technology.
