1. An implantable medical device configured for implantation in a patient comprising:
an antenna;
a sensing module configured to receive a cardiac electrogram of the patient via a plurality of electrodes;
a communication receiver module configured to receive and demodulate signals within a predetermined frequency band for radio-frequency (RF) telemetry communication, wherein the communication receiver module is configured to receive from the antenna and demodulate a first RF telemetry signal emitted by an external device outside of the patient, and receive from the plurality of electrodes and demodulate a first tissue conduction communication (TCC) signal emitted by another implantable medical device implanted within the patient, wherein the first RF telemetry signal and the first TCC signal are within the predetermined band for RF telemetry communication;
a switching module comprising one or more switches, wherein the switching module is configured to selectively couple the plurality of electrodes to either the sensing module or the communication receiver module; and
a processor configured to:
determine a heart rate of the patient based on depolarizations sensed by the sensing module in the cardiac electrogram;
determine that the heart rate is greater than a threshold value; and
change the switching module from a first configuration in which the antenna is coupled to the communication receiver module and the plurality of electrodes are decoupled from the communication receiver module to a second configuration in which the antenna is decoupled from the communication receiver module and the plurality of electrodes are coupled to the communication receiver module in response to the determination that the heart rate is greater than the threshold value.
