SUMMARY NOTES IN THE RECORD s20274 (Duration: 22:56:08.000)
Starting time, recording date: 13:15:00 11/09/1992

Lead 1: 1
Age: 61 Sex: M
Comments:
Records s20271, s20272, s20273 and s20274 are from the same patient.
This is the final record.
The onset of ischemia often begins with peaking of T-waves,
followed by ST depression. Rate increases often lead to
ischemic changes sometimes only T-wave peaking, and sometimes
also ST depression.
Lead 0:
It is easier to annotate since the ST deviation function has
less variability.
Lead 1:
It is more difficult because of its higher variability compound
to ischemic episodes. There are regions particularly seen in
lead 1 after ischemia to the end of the record, where there are
numerous ST shifts, generally associated with heart rate changes,
which are felt to be manifestations of ischemia - some T-wave
peaking, some ST depressions.
Electrode locations were not recorded.
