    From 8:05:58 to 8:47:48
    This period shows heart rate increase and associated
    ST changes consisting of J-point depression and up-sloping
    ST segment of varying magnitude. Multiple regions meet
    strict criteria for "episodes" and are annotated
    individually.
    From 17:38:0 to 18:00:14
    This period shows heart rate increase and associated
    ST changes consisting of J-point depression and up-sloping
    ST segment of varying magnitude.
  Lead 1:
    From 21:08:08 to end
    During this period of heart rate increase there is slight
    peaking of the T-wave and associated ST-segment changes
    which reach the threshold of significance on three
    occasions.
  This recording shows numerous rate-related ST changes.
  This record is from the initial Long-Term ST Database of
  eleven 24-hour ST annotated ambulatory records (record s20563).
