SUMMARY NOTES IN THE RECORD s20391 (Duration: 20:48:28.000)
Starting time, recording date: 18:01:00 21/03/1992
Lead 0: 0
Lead 1: 1
Age: 64 Sex: M
Comments:
This record shows numerous shifts in QRS axis, in the
absence of ischemia. There are some noisy periods.
Lead 0:
There are 2 ischemic episodes.
Lead 1:
There are corresponding ischemic episodes, but one of
them is divided into two separate episodes by a very
brief period of ST deviation which returned to the
normal range.
Electrode locations were not recorded.
