SUMMARY NOTES IN THE RECORD s20281 (Duration: 23:41:59.988) Starting time, recording date: 11:30:00 10/09/1992 Lead 0: 0 Lead 1: 1 Age: 68 Sex: M Comments: This record is realy uninteresting, with few ST-depressions. Lead 1 has less obvious changes. The ST episodes are probably ischemic. Electrode locations were not recorded.
