SUMMARY NOTES IN THE RECORD s20511 (Duration: 19:43:30.000) Starting time, recording date: 14:32:00 29/11/1998 Lead 0: V4 Lead 1: MLIII Age: 61 Sex: F Comments: At 12:28:54 in lead 0 there is an ischemic episode which has an episode of noise within it, and the auto-detected extrema was falsely placed at the noise location. The extrema was relocated manually, and noise annotation was added. The same was done in lead 1.
