Combination trunk vest for cardiac electrophysiological mapping

摘要

To carry out cardiac catheterization.SOLUTION: Cardiac catheterization is carried out by clothing a subject in a torso vest having a plurality of sensing electrodes, magnetic location sensors, active current location sensors and patches for establishing galvanic contact with the skin of the subject. A multi-electrode probe is inserted into a cardiac chamber such that a plurality of intracardiac electrodes are disposed at respective locations in the heart. The respective locations are determined using active current locations, Electrical calibration signals are emitted from the intracardiac electrodes, and received in the sensing electrodes of the torso vest. Relationships between the emitted calibration signals and the received calibration signals are determined in the intracardiac electrodes to map a correspondence between the received calibration signals and the respective locations.SELECTED DRAWING: Figure 1
