Cardiac analysis user interface system and method
Methods of generating a graphical representation of cardiac information on a display screen are provided. The method comprises: electronically creating or acquiring an anatomical model of the heart including multiple cardiac locations; electronically determining a data set of source information corresponding to cardiac activity at the multiple cardiac locations; electronically rendering the data set of source information in relation to the multiple cardiac locations on the display screen. Systems and devices for providing a graphical representation of cardiac information are also provided.
1. A method of generating a graphical representation of cardiac information on a display screen, comprising:
acquiring an anatomical model of the heart including at least one cardiac chamber, including updating the anatomical model at least once every 30 minutes;
electronically determining 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 dipole density information determined for a point on a surface of the heart, surface charge information, temperature information, pH information, 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;
electronically rendering the anatomical model of the heart on the display screen and then rendering an updated anatomical model of the heart on the display screen; and
electronically rendering 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 screen, 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 method of claim 1 , wherein the anatomical model is updated at least once every minute.
3. The method of claim 1 , wherein the anatomical model is updated at least once every second.
4. The method of claim 1 , wherein the anatomical model is updated at least once every 100 milliseconds.
5. The method of claim 1 , wherein the anatomical model is updated at least 30 times per second.
6. The method of claim 1 , wherein the anatomical model is created using data from a CT and/or an Mill scan.
7. The method of claim 1 , wherein the anatomical model is created using signals from at least one ultrasound transducer.
8. The method of claim 7 , wherein the at least one ultrasound transducer is positioned within the heart chamber.
9. The method of claim 1 , wherein the anatomical model of the heart comprises a static model of the heart.
10. The method of claim 1 , wherein the anatomical model of the heart comprises a dynamic model of the heart beating.
11. The method of claim 1 , wherein the multiple sequential data sets of source information represent a dynamic series of information sets.
12. The method of claim 11 , wherein the dynamic series of information sets is updated throughout one or more cardiac cycles.
13. The method 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 method of claim 1 , wherein the source information comprises dipole density data determined for a point on the surface of the heart.
15. The method of claim 1 , wherein electronically determining multiple sequential data sets of source information comprises recording signals from at least one electrode.
16. The method of claim 15 , wherein the at least one electrode comprises multiple electrodes.
17. The method of claim 16 , wherein the multiple electrodes are mounted to an expandable array constructed and arranged for placement within a cardiac chamber.

19. The method 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 method of claim 1 , comprising rendering a data set of field information on the display screen.
21. The method of claim 20 , comprising displaying the data set of field information in an alternating arrangement with the data set of source information.
