Voltage maps created using the2 HDG bipolar
configurations. A. along the spline B. HD wave solution.
The low voltage areas (LVAs)/left atrial (LA) surface was 20.5% (A) and
14.3% (B), respectively. The red tags show the PVI ablation points. The
color-coding was defined as follows: <0.1mV=scar (gray), 0.1
to 0.5mV=diseased atrial tissue, and >0.5mV=healthy atrial
myocardium (purple).
