SUMMARY NOTES IN THE RECORD s20521 (Duration: 18:47:00.000)
Starting time, recording date: 12:25:00 22/04/1998
Lead 0: V4
Lead 1: MLIII
Age: 45 Sex: M
Comments:
Hypertrophic cardiomyopathy in a patient with normal
coronary arteries. There is baseline ST depression that
is down-sloping. There are rate-related episodes of
increased ST depression associated with increased HR,
as seen at 3:20:26, for example. These episodes may be
considered either ischemic or rate-related without
penalty if using this record for algorithm evaluation.
