SUMMARY NOTES IN THE RECORD s20311 (Duration: 23:59:28.000)
Starting time, recording date: 11:51:00 22/08/1985
Lead 0: MLIII
Lead 1: V3
Age: 48 Sex: M
Comments:
Lead 0 shows numerous ST-elevations.
These are mirrored in lead 1 by slight decrease
in baseline ST elevation. There were numerous
rate-related changes in ST level, both elevations
and depressions.
An excerpt of this recording is included in the European
ST-T Database (record e0129).
