SUMMARY NOTES IN THE RECORD s20041  (Duration: 23:54:26.000)

Starting time, recording date:  12:06:00 21/05/1997

Lead 0: 0
Lead 1: 1

Age: 60  Sex: M
Comments:
  This is a difficult record. The baseline ST segment
  is abnormal, it is scooped and slightly depressed.
  There are a number of episodes of ST depression
  associated with increased heart rate, some of which
  are quite prolonged. These events were suggestive of
  ischemia, and were so labeled.
  Lead 0 shows many ischemic episodes and a few axis shifts.
  Lead 1 shows many ischemic episodes, and the morphology of
  the QRST complexes is quite similar to those of lead 0.
  Electrode locations were not recorded.
