1. A system for sensing position of an intracardiac device, comprising:
an intracardiac device configured to be inserted into a patient's heart;
two sensors mounted on the intracardiac device, placed in spaced apart locations and each configured to sense electrical pulses within the patient's heart; and
one or more processors configured to receive one or more signals from each of the two sensors positioned on the intracardiac device, and, based at least in part on one or more signals received from each of the two sensors, the processor is configured to compare a shape of one or more signals received from a first sensor of the two sensors with a shape of one or more signals received from a second sensor of the two sensors to determine a location of a first of the two sensors relative to a location of a second of the two sensors, wherein smaller differences in signal shape indicate that the two sensors are closer together and differences that are larger indicate that the two sensors are further apart.
