SUMMARY NOTES IN THE RECORD s20331 (Duration: 24:23:45.000)
Starting time, recording date: 14:50:00 05/12/1997
Lead 0: V4
Lead 1: MLIII
Age: 85 Sex: M
Comments:
Six episodes, most dramatically seen in lead 0,
of ST depression associated with heart rate increases.
These events are most likely ischemic, and were
labeled as such. In addition, there were a number
of non-ischemic axis shifts. Lead 1 has very low
amplitude.
