1. A cardiac pacing system comprising:

  • at least one leadless cardiac pacemaker configured for implantation in electrical contact with a cardiac chamber and configured to perform cardiac pacing functions in combination with a co-implanted implantable cardioverter-defibrillator (ICD), the at least one leadless cardiac pacemaker comprising a pulse generator configured to generate pulses adapted to perform cardiac pacing and pulses encoding information for transmission as communication signals, and at least two electrodes configured to deliver generated pulses, sense evoked and/or natural cardiac electrical signals, and bidirectionally communicate with a non-implanted programmer by operation of the pulse generator to encode and transmit generated pulses operative as communication signals, the at least one leadless cardiac pacemaker configured to intercommunicate and directly communicate with a non-implanted programmer via pulses generated by the pulse generator and encoded into communication signals wherein transmitted communication power requirements are essentially met by power consumed in cardiac pacing.
