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.
