SUMMARY NOTES IN THE RECORD s20272 (Duration: 23:45:59.988) Starting time, recording date: 09:45:00 28/05/1992 Lead 0: 0 Lead 1: 1 Age: 61 Sex: M Comments: Records s20271, s20272, s20273 and s20274 are from the same patient. This is the second record. Lead 0: Episodes of ST depression preceeded by slight ST elevation and peaking of T waves. Lead 1: There are ST depressions which correspond to episodes seen in lead 0. Both leads show some axis shifting. Electrode locations were not recorded.
