| 20140243695 | METHOD AND SYSTEM FOR EVALUATING STABILITY OF CARDIAC PROPAGATION RESERVE - A method of determining the susceptibility to ventricular arrhythmias in a subject, comprises the steps of: (a) collecting (e.g., by surface EKG or intracardiac EKG) at least one QT and DI interval data set from the subject during a stage of gradually increasing heart rate or a stage of gradually decreasing heart rate; (b) determining (e.g., by applying low- and high pass filtering) low-frequency QT-DI interval trends and high-frequency QT-DI fluctuation signals in said at least one QT and DI interval data set; (c) finding a plurality of correlated and anti-correlated portions between said high-frequency QT-DI fluctuation signals; (d) determining corresponding regression lines for said correlated and anti-correlated portions; (e) finding a plurality of (or in some embodiments all) steady state QT-DI points designated by intersections between said low frequency QT-DI trends and said corresponding regression lines; (f) fitting action potential durations computed from a rate dependent reaction-diffusion model to corresponding ones of said steady state QT-DI points to give (i) a model excitation threshold and (ii) a minimal level of refractoriness at a plurality of (or in some embodiments all of) said steady state QT-DI points; (g) at the steady state QT-DI point corresponding to the highest heart rate in said QT and DI interval data set, determining the difference between said minimal level of refractoriness and a model critical excitation threshold for a stable solitary pulse corresponding to the rate dependent reaction diffusion model of step (f) to give a reserve of refractoriness (RoR); (h) fitting action potential durations computed from a rate dependent reaction-diffusion model to said correlated and anti-correlated portions to give a rate of adaptation of each model excitation threshold to a corresponding steady state value at a plurality of (or in some embodiments all of) said steady state QT-DI points; (i) at the steady state QT-DI point corresponding to the highest heart rate in said QT and DI interval data set, determining the inverse of said rate of adaptation to give a reserve of memory (RoM); (j) combining said reserve of refractoriness (RoR) and said reserve of memory (RoM) to produce a metric of stability-of-propagation reserve (SoPR) in said subject, a higher value of SoPR indicating lower susceptibility to ventricular arrhythmias in said subject. Systems and apparatus for carrying out the method are also described. | 08-28-2014 |
| 20150057723 | METHOD AND SYSTEM OF STIMULATION OF NERVE TISSUE WITH A SEQUENCE OF SPATIALLY DISTRIBUTED RESONANT SUB-THRESHOLD ELECTRICAL STIMULI - The present invention provides a method of stimulating an excitable tissue (e.g., in vitro, in vivo) with a primary electrical stimulus through a primary electrode at a primary stimulation frequency, to produce a propagating action potential in the excitable tissue. The invention is carried out by concurrently stimulating the excitable tissue with a secondary electrical stimulus through at least one secondary electrode at a secondary stimulation frequency. The primary and secondary stimulation frequencies are preferably different from one another. The secondary electrical stimulus preferably has an amplitude not more than one third that of the primary electrical stimulus. Preferably, propagation of the action potential in the excitable tissue is enhanced (e.g., when propagation of action potentials in the tissue is otherwise unstable, partially blocked, or fully blocked). Apparatus for carrying out the method is also described. | 02-26-2015 |
