Abstract
The present disclosure describes cardiac mapping techniques that find particular use in assessing fibrillation, and which also improve the ability to correctly identify local activation time from signals in any rhythm.
Claims22
A method for cardiac mapping of a patient comprising:
- positioning a two-dimensional electrode array at a location in a patient's heart, wherein the two-dimensional electrode array comprises a plurality of electrodes arranged in a nonlinear configuration distributed across the array at known locations and each electrode is separated by a known distance;
- simultaneously detecting at least one local activation signal and activation time at each electrode of the array;
- and
- calculating a conduction velocity (CV) vector for a first electrode of the array using the activation time of the first electrode, the activation time of a second electrode, and the activation time of at least a third electrode;
- thereby to construct a map of cardiac electrical activity.
2 more elements
A method for cardiac mapping comprising the steps of simultaneously obtaining electrode data from an array of at least three electrodes;
- calculating a conduction velocity vector for a first electrode of the array using the activation time of the first electrode, the activation time of a second electrode, and the activation time of at least a third electrode;
- thereby to construct a map of cardiac electrical activity;
- wherein characteristics of said map are unaffected by cardiac or respiratory motion.
