SUMMARY NOTES IN THE RECORD s20301  (Duration: 24:05:15.996)

Starting time, recording date:  12:45:00 16/02/1988

Lead 0: V4
Lead 1: MLIII

Age: 58  Sex: M
Comments:
  Lead 0:
    This lead shows ischemic changes with ST depressions as well
    as axis shifts. Of interest there was one complex episode
    characterized by a salvo of rapid transient ischemic episodes
    superimposed on increasing ST depression.
  Lead 1:
    This lead showed very little ST changes, but had
    some significant axis shifts.
  An excerpt of this recording is included in the European
  ST-T Database (record e0125).
