Abstract
The present invention relates to the technical field of medical electrophysiology catheters, and in particular to a detection system for indicating the degree of contact between catheter electrodes. The system comprises a magnetic field positioning module, a data acquisition module, and an contact detection module. The magnetic field positioning module is used to obtain the relative distance of an electrode relative to a reference point; the data acquisition module is used to obtain the impedance of the electrode relative to the reference point; and the contact detection module locates cells in the total target area based on the relative distance and impedance, and calculates the electrode contact index based on a pre-fitted relationship curve between electrode distance and impedance in the located cells. The contact degree between multiple electrodes and tissue can be obtained in real time. When the electrodes are installed on a catheter, the contact degree between each catheter electrode and tissue is displayed in real time.
