SUMMARY NOTES IN THE RECORD s20081 (Duration: 22:48:49.000)
Starting time, recording date: 12/10/1994
Lead 0: ML2
Lead 1: MV2
Age: 39 Sex: F
Comments:
Lead 0:
The rate-related ECG changes in lead 0 are generally
characterized by J-point depression, ST flattening and
down-sloping, and T-wave inversions. These changes are
highly suggestive of ischemia.
Lead 1:
The few significant rate-related episodes in this lead
show ST flattening and are not likely to represent
ischemia if considered in isolation.
This record is from the initial Long-Term ST Database of
eleven 24-hour ST annotated ambulatory records (record s20538).
