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.
