Abstract

A mapping catheter is positioned in a heart chamber, and active electrode sites are activated to impose an electric field within the chamber. The blood volume and wall motion modulates the electric field, which is detected by passive electrode sites on the preferred catheter. Electrophysiology measurements, as well as geometry measurements, are taken from the passive electrodes and used to display a map of intrinsic heart activity.

CROSS REFERENCE TO RELATED CASES

[0001] This is a Divisional Application of U.S. Ser. No. 09 / 005,105, filed Jan. 9, 1998, entitled “Electrophysiology Mapping System;” which was a Continuation-In-Part of U.S. Ser. No. 08 / 387,832, officially filed May 26, 1995 and entitled “Endocardial Mapping System and Catheter Probe”; which is a national stage application based upon international application PCT / US93 / 09015, filed Sep. 23, 1993; which in turn is a Continuation-In-Part of both U.S. Ser. No. 07 / 950,448, filed Sep. 23, 1992 (now U.S. Pat. No. 5,291,549) and U.S. Ser. No. 07 / 949,690, also filed Sep. 23, 1992 (now U.S. Pat. No. 5,311,866). The parent application, Ser. No. 08 / 387,832, is incorporated by reference herein.FIELD OF THE INVENTION

[0002] The parent invention relates to electrophysiology apparatus which is used to measure and to visualize electrical activity occurring in a patient's heart. The system can display both a visual map of the underlying electrical activity originatin...
