SUMMARY NOTES IN THE RECORD s20011 (Duration: 22:52:59.000)
Starting time, recording date: 17:08:00 09/12/1994
Lead 0: ML2
Lead 1: MV2
Age: 58 Sex: M
Comments:
Lead 0:
All ST change episodes appeared to be rate-related non-ischemic
episodes characterized by J-point depression and scooping of the
ST segment.
Lead 1:
All episodes in lead 1 are compatible with heart-rate induced
non-ischemic changes and are so labeled. It is recognized that
this is an arbitrary decision.
This record is from the initial Long-Term ST Database of
eleven 24-hour ST annotated ambulatory records (record s20689).
