Abstract: Medical devices and methods for making and using medical devices are disclosed. A method of mapping electrical activity of a heart may comprise sensing a plurality of signals with a plurality of electrodes positioned within the heart. The method may further comprise separating the plurality of signals into a first group of signals and a second group of signals, and generating a data set that includes at least one known data point and one or more unknown data points. In some examples, the at least one known data point is generated based on the first group of signals.

Abstract: Methods for displaying physiological mapping data are disclosed. An example method may include storing a set of three-dimensional positional data on a memory, storing a set of metric data on the memory, and storing a set of electrogram data on the memory. The method may also include outputting the set of three-dimensional positional data, the set of two-dimensional metric data, and the set of electrogram data from the memory to a display unit and displaying the set of three-dimensional positional data, the set of two-dimensional metric data, and the set of electrogram data on the display unit as a dynamic display.
