1. An implantable medical device (IMD) comprising:

  • means for acquiring analog signals from cardiac activity;

    means for converting the analog signals to digital signals;

    means for processing the digital signals to identify HIS bundle electrical timing wherein the means for processing include means for subtracting a ventricular signal from an atrial signal to produce a HIS signal; and

    means for computing intervals between the HIS signal and each of the ventricular and atrial signals;

    means for determining the performance of the conduction system based on the monitored intervals.
