SUMMARY NOTES IN THE RECORD s30761 (Duration: 22:44:29.000)
Starting time, recording date: 11:10:00 22/11/1999
Lead 0: E-S
Lead 1: A-S
Lead 2: A-I
Age: 72 Sex: F
Comments:
Patient with coronary artery disease, and resting
electrocardiogram is quite abnormal with ST down-sloping
and biphasic T waves in leads 1 and 2. Ischemic episodes
were present associated with increased heart rate. The
changes were most convincing in lead 2 (with respect to
ST morphology) but episodes were more frequent in lead 1.
