Abstract
A method of cardiac signal processing including: receiving measurements from at least two electrodes positioned within the heart; determining, using the measurements, relative positioning of the at least two electrodes relative to each other; evaluating suitability of the relative positioning of the at least two electrodes for measurement of cardiac activity to determine which cardiac cycles should receive cardiac contractility modulation stimulation.
Claims25
A system for cardiac stimulation comprising:
- an implantable controller, said controller configured to carry out the method of:
- receiving measurements from at least two electrodes positioned within the heart;
- designating, based on said measurements, one electrode of said at least two electrodes as a first electrode, and another electrode of said at least two electrodes as a second electrode;
- generating a signal to cause application of cardiac contractility modulation stimulation to said heart, if a ventricular event is detected at said first electrode and later, after a suitable time delay, at said second electrode.
A method of monitoring comprising:
- monitoring, over time, a time difference between arrival of a cardiac action potential wave-front at two electrodes, each positioned at a different point on a heart;
- based on said monitoring one or more of:
- designating relative position of the two electrodes, based on said time difference, for determination of which cardiac cycles should receive cardiac contractility modulation stimulation.
A system for cardiac stimulation comprising:
- an implantable controller, said controller configured to carry out the method of:
- receiving measurements from at least two electrodes positioned within the heart;
- designating, from said measurements, a first electrode of said at least two electrodes and a second electrode of said at least two electrodes;
- wherein said designating comprises monitoring said measurements for a plurality of cardiac cycles and designating said first electrode for an electrode of said at least two electrodes which senses a ventricular event first for more than half of said cardiac cycles;
- applying cardiac contractility modulation stimulation to said heart if a ventricular event is detected at said first electrode and then at said second electrode after a suitable time delay.
A system for cardiac stimulation comprising:
- an implantable controller, said controller configured to carry out the method of:
- receiving measurements from at least two electrodes positioned within the heart;
- designating, from said measurements, a first electrode of said at least two electrodes and a second electrode of said at least two electrodes;
- wherein said designating comprises identifying, from said measurements, timing of arrival of a cardiac action potential wave-front at said at least two electrodes;
- applying cardiac contractility modulation stimulation to said heart if a ventricular event is detected at said first electrode and then at said second electrode after a suitable time delay.
