SUMMARY NOTES IN THE RECORD s20261  (Duration: 22:27:34.000)

Starting time, recording date:  10:30:00 18/05/1993

Lead 0: 0
Lead 1: 1

Age: No data  Sex: No data
Comments:
  Both leads show baseline ST depression and T inversion.
  The patient probably has left ventricular hypertrophy by
  amplitude criteria. There are episodes of increased ST
  depression and more dramatic T inversion which are ischemic
  like associated with increased heart rate. Cannot rule
  out the possibility of rate-related changes. There are
  also a number of axis shifts.
  Electrode locations were not recorded.
