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).
