Abstract
The invention discloses a method, a system, a computer program and a device for determining the surface charge and/or dipole densities on heart walls. Using the foregoing, a table of dipole densities ν(P′, t) and/or a table of surface charge densities ρ(P′, t) of a given heart chamber can be generated.
Claims22
A cardiac activity mapping system, comprising:
- a probe comprising at least one electrode configured to record electrical potential data Ve from a heart chamber;
- a display apparatus;
- and
- a special purpose computer configured to:
- transform the recorded electrical potential data Ve into cellular membrane dipole density data ν as a distribution across an area of an endocardial surface of the heart chamber;
- generate a map of the distribution of cellular membrane dipole density data ν;
- and
- display the map on the display apparatus.
