    From 9:34:42 to 9:43:32
    This episode of ischemia has produced a biphasic ST pattern,
    beginning with ST-elevation and T-wave peaking, and ending
    with ST depression during the recovery phase. This general
    pattern is seen in other ischemic episodes in this subject
    as well (as at 12:22:28).
    From 14:21:04 to 14:25:36
    This episode begins with ST-depression, with subsequent
    elevation and terminal depression.
  Lead 1:
    From 4:54:22 to 4:55:44
    The minor ST-T changes seen include ST flattening and T-wave
    inversion with respect to the local reference region. These
    changes correspond to clear-cut ischemic changes in lead 0
    at the same time. This phenomena pertains to most of the
    episodes marked in this lead.
    From 8:08:00 to 8:09:16
    The minor ST-T changes seen include ST flattening and T-wave
    inversion with respect to the local reference region. These
    changes correspond to clear-cut ischemic changes in lead 0
    at the same time. This phenomena pertains to most of the
    episodes marked in this lead.
    From 9:01:30 to 9:02:20
    The minor ST-T changes seen include ST flattening and T-wave
    inversion with respect to the local reference region. These
    changes correspond to clear-cut ischemic changes in lead 0
    at the same time. This phenomena pertains to most of the
    episodes marked in this lead.
