Abstract

State machine interface system, comprising state machine algorithms and a graphical user interface, adapted to receive signals from at least one sensor device, that are related to physiological activities of the heart and/or the circulatory system of a living being. The state machine algorithms are adapted to determine phases of heart cycles based upon said signals. The different phases of the heart cycle are determined by said state machine algorithms in a heart cluster state machine simulating the heart, and optionally the circulatory system, achieved by fusions of finite heart muscle cell state machines to form a ΔV-pump state machine. The determined heart cycle phases are evaluated by determining their respective local state diagram based upon said signal such that the respective correct time duration is determined for each heart cycle phase, and then determining the most representative global state diagram. The determined local and global state diagrams are presented at the graphical user interface such that the temporal relations between the different phases are illustrated.
