Abstract

A method is provided. The method includes pacing, by electrodes of a catheter, a heart tissue with pulses. The method includes observing, by the electrodes, a period of electrophysiological repolarization for the heart tissue. The period of electrophysiological repolarization is caused by the pacing. The method also includes measuring, by the electrodes, an electrical signal within the heart tissue after the period of electrophysiological repolarization.

First claim

What is claimed is:

1. A method comprising:
pacing, by a plurality of electrodes of a catheter, a heart tissue with a plurality of pulses;
detecting, by the plurality of electrodes of the catheter, a period of electrophysiological repolarization for the heart tissue caused by the pacing;
measuring, by the plurality of electrodes of the catheter, an electrical signal within the heart tissue after the period of electrophysiological repolarization; and
measuring, by the plurality of electrodes of the catheter, an activity pattern of returning electrical signals after the electrical signal is measured in the heart tissue, the returning electrical signals propagating from the heart tissue.

2. The method of claim 1 , wherein each electrode of the plurality of electrodes provides a pulse of the plurality of pulses.

3. The method of claim 1 , wherein the period of electrophysiological repolarization comprises a time period when the heart tissue is in a refractory period.

4. The method of claim 1 , further comprising:
isolating and analyzing focal points of interest within the heart tissue based on the activity pattern across the plurality of electrodes.

5. The method of claim 1 , wherein the catheter comprises a mesh, balloon, or spoon catheter.

6. The method of claim 1 , wherein the plurality of electrodes comprises at least forty electrodes.

7. The method of claim 1 , wherein each pulse of the plurality of pulses are paced together and at a same time.

8. The method of claim 1 , wherein the plurality of pulses are paced to control a time between each pacing.

9. The method of claim 1 , wherein each of a number or a location of the plurality of pulses is varied to manipulate the period of electrophysiological repolarization.

10. The method of claim 1 , wherein an isolated section of the heart tissue is paced.

11. An apparatus comprising:
a catheter comprising a plurality of electrodes; and
a cardiac pacing and diagnosis device comprising a memory storing processor executable instructions of cardiac pacing and diagnosis software, and a processor configured to execute the processor executable instructions of the cardiac pacing and diagnosis software to cause the apparatus to:
pace, by the plurality of electrodes of the catheter, a heart tissue with a plurality of pulses;
detect, by the plurality of electrodes of the catheter, a period of electrophysiological repolarization for the heart tissue caused by the pacing;
measure, by the plurality of electrodes of the catheter, an electrical signal within the heart tissue after the period of electrophysiological repolarization; and
measure, by the plurality of electrodes of the catheter, an activity pattern of returning electrical signals after the electrical signal is measured in the heart tissue, the returning electrical signals propagating from the heart tissue.

12. The apparatus of claim 11 , wherein each electrode of the plurality of electrodes provides a pulse of the plurality of pulses.

13. The apparatus of claim 11 , wherein the period of electrophysiological repolarization comprises a time period when the heart tissue is in a refractory period.

14. The apparatus of claim 11 , wherein the processor is configured to execute the processor executable instructions of the cardiac pacing and diagnosis software to cause the apparatus to:
isolate and analyze focal points of interest within the heart tissue based on the activity pattern across the plurality of electrodes.

15. The apparatus of claim 11 , wherein the catheter comprises a mesh, balloon, or spoon catheter.

16. The apparatus of claim 11 , wherein the plurality of electrodes comprises at least forty electrodes.

17. The apparatus of claim 11 , wherein each of the plurality of pulses are paced together and at the same time.

18. The apparatus of claim 11 , wherein the plurality of pulses are paced to control a time between each pacing.
