SUMMARY NOTES IN THE RECORD s20601 (Duration: 23:40:00.000)
Starting time, recording date: 14:44:00 11/07/1988
Lead 0: V4
Lead 1: MLIII
Age: 46 Sex: F
Comments:
There is an ischemic episode in lead 1 at 22:22:30
which is corrupted with noise. This patient demonstrated
a few ischemic episodes, manifested by ST depression
in both leads. The changes were minimal, and in some
cases the associated heart rate increases introduced
severe noise.
