1. A medical system comprising:
a tubular shaft having a proximal end and a distal end, the tubular shaft extending along a longitudinal axis;
an expandable basket assembly coupled to the distal end of the tubular shaft, the expandable basket assembly comprising:
a plurality of splines configured to bow radially outward from the longitudinal axis; and
a plurality of electrodes attached to the plurality of splines;
a processor; and
a memory in communication with the processor and storing instructions configured to cause the system to:
receive a first signal indicative of electrical activity in myocardial tissue, the first signal being received from the plurality of electrodes;
receive a second signal indicative of a respective position of the plurality of electrodes;
determine a geometric center of the plurality of electrodes;
determine a focus of an arrhythmia in the myocardial tissue;
output, to a display, a geometric shape corresponding to an area proximate the geometric center;
output, to the display, a region indicative of the focus of the arrhythmia; and
output, to the display, an indication of a spatial relationship between the geometric center and the focus of the arrhythmia.
