System and method for electrophysiological mapping

A method of visualizing an electrophysiology map of a portion of a patient's anatomy using an electroanatomical mapping system, the method comprising:

• the electroanatomical mapping system receiving a plurality of electrophysiology data points, the plurality of electrophysiology data points comprising a plurality of electrophysiology signals;
• the electroanatomical mapping system creating a histogram of values of a characteristic of the plurality of electrophysiology signals;
• the electroanatomical mapping system analyzing the histogram of values to determine a most dominant value;
• the electroanatomical mapping system defining a display convention for a graphical representation of the characteristic;
• and
• the electroanatomical mapping system outputting the graphical representation of the characteristic according to the display convention,
• wherein a range of the display convention is centered at the most dominant value.

A system for visualizing an electrophysiology map of a portion of a patient's anatomy, comprising:

• a visualization processor configured to:
• receive as input a plurality of electrophysiology data points, the plurality of electrophysiology data points comprising a plurality of electrophysiology signals;
• create a histogram of values of a characteristic of the plurality of electrophysiology signals;
• analyze the histogram of values to determine a best-fit curve to the histogram;
• define a display convention for a graphical representation of the characteristic based upon a shape of the best-fit curve to the histogram;
• and
• output the graphical representation of the characteristic according to the display convention.
