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.
