Abstract:
1. A method for stabilization of cardiac tissue contractions using limit cycles, the method comprising: selecting a desired limit cycle in Poincare space which is indicative of a desired state of a heart; mapping, in real time, a measured limit cycle in Poincare space based on measurements obtained from a first electrode disposed on the heart; applying a stimulus pulse with an energy of less than 0.1 joules to the heart from the first electrode, wherein the stimulus pulse induces an altered limit cycle that is different than the measured limit cycle; observing a change, in real time, in the altered limit cycle in response to the stimulus pulse and constructing a vector of the change; observing a difference between the altered limit cycle and the desired limit cycle; applying an intervention pulse from the first electrode if the difference exceeds a limit cycle threshold or waiting for a waiting period if the difference is within the limit cycle threshold, wherein the intervention pulse is configured to move the altered limit cycle toward the desired limit cycle.
