1. A system comprising:

  • first, second, and third input terminals to receive heart signals from respective external first, second, and third electrodes attached to a subject;

    at least one pace pulse detector circuit, coupled to the first, second, and third input terminals, to detect from the heart signals first and second pace pulses delivered to different locations of the heart, the pace pulse detector circuit comprising an amplifier circuit to provide polarity information about the first and second pace pulses; and

    a logic circuit, coupled to the pace pulse detector circuit, to assign a first location assignment to the first and a second location assignment to the second pace pulse using at least in part the polarity information about the first and second pace pulses.
