Vector mapping of three-dimensionally reconstructed intrabody organs and method of display

摘要

Method of diagnosing an abnormal condition in the present invention biological structure, such as the heart of the steps of measuring a physiological response at at least three sampled points on the biological structure surface, calculating a vector function for said reaction, the vector function and a display step of displaying, a step to evaluate the abnormal state from the display. The present invention is particularly useful for diagnosing cardiac arrhythmias (cardiac arrhythmias) is a local activation time evaluation in the case of the physiological response to the voltage, the vector function is a change in the local activation time is also in particular, conduction velocity. ; Heart, sample point, physiological responses, vector functions, local activation time
