Abstract

Claims (36)

1. A system of generating a graphical representation of cardiac information on a display screen, comprising:

a processor to acquire an anatomical model of a heart including at least one cardiac chamber, and to update the anatomical model at least once every 30 minutes;

sensors to electronically determine multiple sequential data sets of source information corresponding to cardiac activity at multiple cardiac locations of the at least one cardiac chamber, the source information comprising surface potential information, temperature information, pH information, processor-determined dipole density information or surface charge information for a point on a surface of the heart, or a combination of two or more thereof,

wherein the multiple sequential data sets of source information are electronically determined at least once per second;

a display, wherein the processor is configured to electronically render the anatomical model of the heart on the display and then render an updated anatomical model of the heart on the display, wherein rendering the updated anatomical model includes displaying tissue motion for the at least one cardiac chamber; and

the processor is configured to electronically render calculated information based on the data sets of source information in relation to the multiple cardiac locations of the anatomical model or the updated anatomical model of the heart on the display, including:

rendering the calculated information as an instantaneous map of cardiac activation across the entire at least one cardiac chamber that graphically differentiates values of the calculated information overlaid on the anatomical model.

2. The system of claim 1 , wherein the processor is configured to update the anatomical model at least once every minute.

3. The system of claim 1 , wherein the processor is configured to update the anatomical model at least once every second.

4. The system of claim 1 , wherein the processor is configured to update the anatomical model at least once every 100 milliseconds.

5. The system of claim 1 , wherein the processor is configured to update the anatomical model at least 30 times per second.

6. The system of claim 1 , wherein the processor is configured to create the anatomical model using data from a CT and/or an MRI scan.

7. The system of claim 1 , wherein the processor is configured to create the anatomical model using signals from at least one ultrasound transducer.

8. The system of claim 7 , wherein the ultrasound signals are from at least one ultrasound transducer positioned within the heart chamber.

9. The system of claim 1 , wherein processor is configured to create an anatomical model of the heart that comprises a static model of the heart.

10. The system of claim 1 , wherein processor is configured to create an anatomical model of the heart that comprises a dynamic model of the heart beating.

11. The system of claim 1 , wherein the multiple sequential data sets of source information represent a dynamic series of information sets.

12. The system of claim 11 , wherein the system is configured to update the dynamic series of information sets throughout one or more cardiac cycles.

13. The system of claim 1 , wherein the source information is data representing, at a location in 3D space, a physical property or properties discrete to the specific location in 3D space.

14. The system of claim 1 , wherein the source information comprises dipole density data determined for a point on the surface of the heart.

15. The system of claim 1 , wherein electronically determining multiple sequential data sets of source information comprises the processor configured to record signals from at least one electrode.

16. The system of claim 15 , wherein the at least one electrode comprises multiple electrodes.

17. The system of claim 16 , wherein the multiple electrodes are mounted to an expandable array constructed and arranged for placement within a cardiac chamber.

18. The system of claim 1 , wherein the processor is configured to present the calculated information in the form of, or using, a differentiating map.

19. The system of claim 18 , wherein the differentiating map comprises a map of value differentiating parameters including:

color;

contrast;

brightness;

hue;

saturation level; or

combinations of two or more thereof.

20. The system of claim 1 , comprising the processor configured to render a data set of field information on the display.

21. The system of claim 20 , comprising the processor configured to display the data set of field information in an alternating arrangement with the data set of source information.

22. The system of claim 1 , further comprising:

the processor configured to acquire updated anatomical data from one or more ultrasound transducers located within the at least one cardiac chamber; and

to update the anatomical model based, at least in part, on the updated anatomical data.
