SUMMARY NOTES IN THE RECORD s20331  (Duration: 24:23:45.000)

Starting time, recording date:  14:50:00 05/12/1997

Lead 0: V4
Lead 1: MLIII

Age: 85  Sex: M
Comments:
  Six episodes, most dramatically seen in lead 0,
  of ST depression associated with heart rate increases.
  These events are most likely ischemic, and were
  labeled as such. In addition, there were a number
  of non-ischemic axis shifts. Lead 1 has very low
  amplitude.
