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).
