Spatial Resolution

GARBAGE IN, GARBAGE OUT.

The electrograms speak for themselves.

Fractionation: decreased accuracy

Standard Electrodes:
Ambiguous Excitation Time

Ultra-High Resolution = Greater Mapping Accuracy

CoreMap Electrodes:
Clear Excitation Time

A unipolar electrode ‘sees’ laterally.

The top electrode ‘sees’ same laterally, but can’t see through the bottom electrode.

Thus with an orthogonal bipolar pair the “difference” signal is
the footprint beneath the bottom electrode.
