32. A cardiac pacing system comprising:
a leadless cardiac pacemaker configured for implantation in electrical contact with a cardiac chamber and configured for delivering a pacing pulse and encoding outgoing communication in the pacing pulse whereby a power requirement for the outgoing communication adds nothing to a power requirement for current in delivering the pacing pulse. - View Dependent Claims (33, 34)

35. A method for communicating in an implantable device comprising:
-
generating stimulation pulses at an implanted biostimulator;
encoding information onto generated stimulation pulses at the implanted biostimulator by selective alteration of stimulation pulse morphology that is benign to therapeutic effect and energy cost of the stimulation pulse; and
conducting the stimulation pulses into body tissue via electrodes for antenna-less and telemetry coil-less communication. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
