摘要
The invention relates to a method for using tissue contact technology to optimize automated cardiac chamber mapping algorithms to both speed up the mapping process and guarantee the definition of the actual chamber limits. The invention further comprises a method for conveying tissue type information to such automatic mapping algorithms so as to allow them to adapt their point collection density within areas of particular interest. The method is enhanced by the use of a magnetic chamber that employs electromagnetic coils configured as a waveguide that radiate magnetic fields by shaping the necessary flux density axis on and around the catheter distal tip so as to push, pull and rotate the tip on demand and as defined by such automatic mapping algorithms.
