SUMMARY NOTES IN THE RECORD s20531 (Duration: 19:47:00.000)
Starting time, recording date: 15:09:00 15/04/1999
Lead 0: V4
Lead 1: MLIII
Age: 70 Sex: M
Comments:
This record shows intermittent LBBB with numerous changes in conduction.
At some times the alteration in conduction was so rapid that the ST
deviation function showed only low-amplitude oscillations, and these
were "tracked out" by the annotators (see 16:26:10 in lead 1). No
ischemia was found in this record. The variation in QRS shape also
resulted in fiducial point slip and subsequent ST-level deviations
that were not specially annotated but were tracked out.
