SUMMARY NOTES IN THE RECORD s20191  (Duration: 24:00:00.000)

Starting time, recording date:  10:20:00 16/11/1991

Lead 0: MLIII
Lead 1: V4

Age: 66  Sex: M
Comments: 
  Lead 0:
    From 1:11:14 to 1:12:54
    This region is too noisy to annotate with any certainty
    but is quite likely an ischemic episode.
  Lead 1:
    From 1:28:42 to 1:30:16
    Slight elevation of ST segment and increase in its positive
    slope is seen. This change correlates with more definite
    ischemic change in lead 0. Thus, this episode is labeled
    "ischemic".
