Title:
TISSUE CONDUCTION VELOCITY
Document Type and Number:
Japanese Patent JP2018175860
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an improved method for measuring conduction velocity in the heart of a living subject.SOLUTION: A method includes capturing a bipolar signal from a first electrode and a second electrode contacting a first location and a second location, respectively, in the heart of a living subject. The method further includes capturing a unipolar signal from the first electrode while in contact with the first location, and deriving from the bipolar signal and the unipolar signal a point in time at which the first location is generating the unipolar signal. The method also includes computing a metric for a conduction velocity of the unipolar signal at the first location on the basis of a shape of the unipolar signal at the point in time.SELECTED DRAWING: Figure 1
