ABSTRACT:
A system for aiding in the positioning of a catheter. The system includes a basket shaped catheter having a plurality of bipoles arranged thereon for sensing voltage potentials generated by tissue. An analog to digital converter is coupled to the catheter and configured to convert the sensed voltage potentials to digital signals. A computer is coupled to the analog to digital converter and to a video display and is programmed to calculate an absolute value of a slope of each of the digital signals. The computer is also programmed to generate and display on the video display a graphical representation of the absolute values of the slopes on a first image corresponding to the catheter. A method of aiding in the positioning of a catheter against a tissue surface is also disclosed.
