        This unusual record demonstrates intermittent pre-excitation that
  results in considerable variability of the ST segment.  During
  pre-excitation there is a depression in the ST segment. When alteration
  in the conduction pattern is rapid, the average ST segment as displayed
  by SEMIA shows minimal sustained change. When conduction shifts and
  remains consistent for minutes, then the ST segment changes significantly.
  To make matters more complicated, the degree of pre-excitation often
  varies, producing intermediate QRS and ST morphological forms. This
  record shows some rate-related episodes.
