SUMMARY NOTES IN THE RECORD s20231 (Duration: 23:25:45.000) Starting time, recording date: 08:09:00 17/07/1996 Lead 0: ML2 Lead 1: MV2 Age: 53 Sex: M Comments: Lead 0: Episode of paroxysmal atrial fibrillation, onset at 04:26:37, offset at 05:45:07. There are rate-related ST episodes in the same interval. Lead 1: Episode of paroxysmal atrial fibrillation, the same period as in lead 0. There is rate-related ST depression which begins near atrial fibrillation onset at 04:26:41, but terminates by 05:25:13.
