SUMMARY NOTES IN THE RECORD s20381  (Duration: 23:50:49.988)

Starting time, recording date:  11:49:00 14/02/1992

Lead 0: 0
Lead 1: 1

Age: No data  Sex: No data
Comments: 
  There is one clear ischemic episode at the end of
  the record, present in both leads. In lead 0 there
  were a few very minor ST depressions which met the
  criteria for significance, and which were felt to
  be "rate-related". These changes were not present
  in lead 1. There were periods of noise in the data.
  Electrode locations were not recorded.
