Abstract
Provided is a cardiac virtualization test tank and testing system and method. A test tank is provided that includes a physical heart model representing the structure of the heart and a plurality of electrodes that output simulated biopotential signals based on an EP model representing the electrophysiological activity of the heart. The test system can be used for training, teaching, or validating a cardiac mapping, diagnosis, and/or treatment system, as examples.
Claims21
A cardiac virtualization system, comprising:
- a test tank defining a test volume;
- a physical heart model disposed within the test tank and representing a heart surface and/or at least one heart chamber surface;
- a plurality of virtualization electrodes disposed at select locations relative to the physical heart model;
- and
- test electronics configured to drive the plurality of virtualization electrodes to generate simulated biopotentials within the test tank as if produced by a heart or at least one heart chamber at the location of the physical heart model,
- wherein the virtualization electrodes are configured to simulate a surface charge density pattern and/or a dipole density pattern under the heart surface and/or under the at least one heart chamber surface.
