Abstract
In general, the invention is directed to methods and devices for electrically stimulating heart tissue. The invention includes delivery of stimulation to transplanted biological material, such as transplanted cells, transplanted in a myocardium of a heart during an ejection phase of a cardiac cycle. The invention also includes delivery of cardiac potentiation therapy stimulation, which improves the hemodynamic performance of the heart. Stimulation to transplanted biological material and cardiac potentiation therapy stimulation can improve the performance of a heart damaged by myocardial infarction.
Claims27
A method comprising:
- electrically stimulating biological material transplanted in a myocardium of a heart during an ejection phase of a cardiac cycle;
- and
- electrically stimulating a chamber of the heart to induce post-extrasystolic potentiation.
A computer-readable medium comprising instructions for causing a programmable processor to:
- electrically stimulate biological material transplanted in a myocardium of a heart during an ejection phase of a cardiac cycle;
- and
- electrically stimulate a chamber of the heart to induce post-extrasystolic potentiation.
A system comprising:
- a first electrode configured to deliver a first electrical stimulation to biological material transplanted in a myocardium of the heart;
- a second electrode configured to deliver a second electrical stimulation to a chamber of a heart;
- and
- a processor configured to control delivery of the first stimulation during an ejection phase of a cardiac cycle and further configured to control delivery of the second stimulation to induce a post-extrasystolic potentiation.
A system comprising:
- first stimulating means for electrically stimulating biological material transplanted in a myocardium of a heart;
- second stimulating means for electrically stimulating a chamber of the heart;
- and
- processing means for controlling the first stimulating means to deliver the electrical stimulation when the heart is in the ejection phase, and for controlling the second stimulating means to induce post-extrasystolic potentiation.
