Comments:
This is a very difficult record. There are a number of
definite ischemic episodes which are associated with
increases in heart rate. Some of the lower amplitude
episodes are ambiguous (ischemia vs. rate-related ST
changes). Most of those that had a characteristic
temporal course and that showed a slight amount of
ST flattening were labeled as ischemic episodes. There
were definitely a couple of long episodes that were
rate-related.
Electrode locations were not recorded.
