Abstract
A computer-implemented method includes measuring, using a first sense channel, a first electrode impedance signal associated with a first electrode. The method further includes measuring, using a second sense channel, a second electrode impedance signal associated with at least a second and third electrode, wherein the second and third electrodes are electrically connected to each other but not to the first electrode. The method further assesses tissue contact/proximity based on the first electrode impedance signal and the second electrode impedance signal.

A computer-implemented method of assessing tissue contact for a plurality of electrodes located on a medical device, the method comprising:
- measuring, using a first sense channel, a first electrode impedance signal associated with a first electrode;
- measuring, using a second sense channel, a second electrode impedance signal associated with at least a second and third electrode, wherein the second and third electrodes are electrically connected to each other but not to the first electrode;
- and
- assessing tissue contact/proximity based on the first electrode impedance signal and the second electrode impedance signal.
A computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method of assessing tissue contact for a plurality of electrodes located on a medical device, the method comprising:
- measuring, using a first sense channel, a first electrode impedance signal associated with a first electrode;
- measuring, using a second sense channel, a second electrode impedance signal associated with at least a second and third electrode, wherein the second and third electrodes are electrically connected to each other but not to the first electrode;
- and
- assessing tissue contact/proximity based on the first electrode impedance signal and the second electrode impedance signal.
