1. A method comprising:

  • providing at least two implantable electrostimulation electrodes in contact with cardiac tissue, the at least two implantable electrostimulation electrodes electrically coupled to a current-controlled implantable pulse generator;

    generating a wireless control signal to control sourcing, or sinking, of an electrostimulation current, the wireless control signal generated using an implantable controller separate and distinct from (1) the electrostimulation electrodes and (2) the current-controlled implantable pulse generator, and the implantable controller wirelessly coupled to the current-controlled pulse generator;

    sourcing a current to one or more implantable electrostimulation electrodes in response to the received wireless control signal;

    sinking a current from one or more implantable electrostimulation electrodes in response to the received wireless control signal; and

    instantaneously balancing the total current sourced with a total current sunk concurrently.
