Abstract
An elongate probe apparatus (20) for insertion into the body of a subject, comprising: a structure (24) having a substantially rigid configuration; a plurality of physiological sensors (26, 28, 30), which generate signals responsive to a physiological activity, said sensors (24, 28, 30) having substantially fixed positions on said structure (24) in said configuration; and one or more devices that generate position signals indicative of the positions of the physiological sensors on said structure in said configuration.
Claims14
A method for determining a velocity relating to physiological activity at a location in a tissue, comprising:
- receiving signals indicative of physiological activity at a plurality of known positions adjacent to the location in the tissue;
- measuring a respective characteristic time at each of the plurality of positions using the signals received therefrom;
- computing velocity component vectors along two non-parallel axes, wherein the velocity component vectors are defined by the known positions and the measured activation times;
- and
- applying vector arithmetic operations to the velocity component vectors to determine the velocity at the location.
