SUMMARY NOTES ST ANNOTATIONS IN THE RECORD s30791 (Duration: 23:09:59.000)
Starting time, recording date: 01/12/1999
Lead 0: E-S
Lead 1: A-S
Lead 2: A-I
Age: 74 Sex: M
Comments:
The electrocardiogram at baseline is abnormal with
ST concave depression. There also seems to be left
axis deviation. The record shows numerous axis shifts.
There are several episodes of ischemia related to
increased heart rate, documented in all three leads.
In the lead 0, however, the ST changes would be
defined as rate-related if considered in isolation.
They have been labeled as "ischemic" in light of
the full 3-lead picture.
