Abstract
A method of constructing a cardiac map of a heart having a heart cycle including; bringing an invasive probe into contact with a location on a wall of the heart; determining, at at least two different phases of the heart cycle, a position of the invasive probe; and determining a local non-electrical physiological value at the location. The method is repeated for a plurality of locations in the heart. The positions are combined to form a time-dependent map of at least a portion of the heart and local relationships between changes in positions of the invasive probe and determined local non-electrical physiological values are determined. Preferably, local electrical activity at the plurality of locations is also acquired.

67. A method of determining the structure of at least a portion of a heart having a heart cycle comprising:
-
(a) bringing a probe into contact with a location on a wall of the heart; (b) determining a position in space of the probe at the location; (c) acquiring data at the position in space; (d) repeating (a), (b) and (c) for a multiplicity of locations of the heart to determine a multiplicity of data each associated with a determined position of the probe in space; and (e) combining the multiplicity of the data and the determined positions of the probe in space to determine a map, containing said data, of at least a portion of the heart, said positions in space being determined solely from information other than that derived from an image of the vicinity of the probe at the locations. - View Dependent Claims (68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78)
