Patent ID: 8923959

Claim:
A method of providing cardiac mapping comprising the steps of: placing at least two catheters in the heart of a patient, wherein each of said catheters comprising at least one electrode pair, sensing an electrical signal arriving at said electrode pairs of each of said catheters; acquiring a heart fluoroscopic image of a patient and placing visual indicators on said heart fluoroscopic image which are positioned at and correspond with an image of said electrode pairs of said catheters and which detect said electrical signal arriving at said electrode pairs; and using a programmed computer, displaying, on a visual display, a visual indication of cardiac signal timing information, the visual indication being superimposed on said heart fluoroscopic image of the patient for said electrode pairs of each of said catheters, wherein the detection of said electrical signal at each of said electrode pairs of each of said catheters occurs at multiple regions of the heart substantially proximate in time with respect to each other and wherein the visual indication is displayed in real time with the detection of said electrical signal.
