State machine interface system
First Claim
1. A method for graphical representation of time-related heart cycle state diagrams based on measured heart functions and heart pumping models, the method comprising:
- measuring one or more heart functions of a patient, the measuring selected from one or more of ultrasound imaging, electrocardiogram, magnetic resonance imaging, spinning computer aided tomography, strain rate imaging, x-ray imaging, gamma radiation imaging, pulse plethysmography, oximetry, tissue velocity imaging, pulse measuring, flow measuring, pressure measuring, or volume measuring;
analyzing the measured heart functions using a dynamic displacement pumping model of a heart using one or more processing devices, the pumping model determining heart cycle states by simulating heart pumping, and by identifying durations of heart cycles, from the measured heart functions; and
displaying a graphical model of the heart cycle states on a graphical user interface such that a temporal relation between different heart cycle states is depicted in a single state diagram.

Abstract
State machine interface system, heart state machine analyzer and/or stimulator, 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 the state machine algorithms determine states of heart cycles based upon the signals. The determined heart cycle states are graphically presented at the graphical user interface such that the temporal relation between the different states are illustrated. The graphical user interface may be circular diagrams or bar graphs including parts representing the temporal relation between the different states.
