1. A method of utilizing no more than three ICG/ECG electrode pairs to sense both ICG and heart electrical activity signals, the method comprising:

  • sensing, with a first electrode contact and a second electrode contact of a first pair of the no more than three ICG/ECG electrode pairs, a first ICG signal and a first heart electrical activity signal;

    sensing, with a first electrode contact and a second electrode contact of a second pair of the no more than three ICG/ECG electrode pairs, a second ICG signal and a second heart electrical activity signal;

    sensing, with a first electrode contact and a second electrode contact of a third pair of the no more than three ICG/ECG electrode pairs, a third ICG signal and a third heart electrical activity signal;

    utilizing different clocks to sense the first, second and third ICG signals and the first, second and third heart electrical activity signals;

    synchronizing the different clocks, thereby time-synchronizing the sensed first, second and third ICG signals with the first, second and third heart electrical activity signals; and

    determining a cardiac parameter based on the first, second and third ICG signals and an EKG signal based on the first, second and third heart electrical activity signals.
