Abstract

Systems, devices and methods are provided for displaying statistical distributions of cardiac events. A device embodiment comprises circuitry adapted to communicate with a medical device that is adapted to acquire data regarding cardiac events occurring at two or more cardiac sites, and display means for displaying a histogram of the data as two or more statistical distributions for the two or more cardiac sites. The histogram includes a number of histogram bins. At least one of the histogram bins includes both a representation for at least a portion of a statistical distribution of a cardiac event for a first cardiac site and a representation for at least a portion of a statistical distribution of a cardiac event for a second cardiac site. Other embodiments are provided herein.
