Systems and methods for communication between medical devices

A medical device comprising:

• one or more electrodes;
• and
• a controller connected to the one or more electrodes, the controller configured to:
• receive a conducted communication signal via the one or more electrodes, the conducted communication signal comprises:
• a signal component that includes a plurality of communication pulses in a pulse pattern communicated from an external medical device;
• and
• a noise component that includes noise signals;
• and
• determine if the received conducted communication signal comprises one or more pulses that do not match the pulse pattern of the communication pulses, and when so, adjust a receive threshold to further filter out the noise signals from the received conducted communication signal.
