SUMMARY NOTES IN THE RECORD s30681 (Duration: 23:39:35.984)
Starting time, recording date: 11:35:00 14/01/1999
Lead 0: V6
Lead 1: II
Lead 2: V5
Age: 71 Sex: M
Comments:
Patient with CAD and hypertension has many episodes
of ST depression recorded simultaneously on all
leads. The ST segments are associated with heart
rate increases, and with different ST shape. Most
are J-point depressions with up-sloping ST segments,
but a very convincing episode occurred at the end of
the recording period with clearly ischemic, down-sloping
ST segments.
