1. A leadless cardiac pacemaker (LCP) for implantation in a patient's heart, comprising:
sensing circuitry configured to sense cardiac electrical activity of the patient's heart;
pacing circuitry configured to provide pacing therapy to the patient's heart based at least in part on the sensed cardiac electrical activity sensed by the sensing circuitry; and
communication circuitry for communicating with another device, wherein the communication circuitry is configured to communicate with the other device using low-voltage communication pulses, encoded with data, that are conducted through the patient's heart via conduction provided by cardiac tissue of the patient's heart, wherein the low-voltage communication pulses are configured to not cause a reaction in the cardiac tissue of the patient's heart.
