1. State machine interface system, comprising state machine algorithms and a graphical user interface, adapted to receive signals from a sensor device, that are related to physiological activities of the heart and/or the circulatory system of a living being and said state machine algorithms determine states of heart cycles based upon said signals, wherein said different states 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, characterized in that said determined heart cycle states being graphically presented at the graphical user interface such that the temporal relation between the different states are illustrated.
