#Comments:
# 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.
