#Comments:
#  Records s20271, s20272, s20273 and s20274 are from the same patient.
#  This is the first record.
#  Lead 0:
#    This record shows multiple episodes of ischemia which
#    typically show T-wave peaking followed by significant
#    ST depression. Some episodes trigger the ischemic
#    episode definition during the ST elevation, while
#    others trigger only at the onset of ST-depression.
#    In still other cases there is a short interval of
#    "near-baseline" ST between the elevations (peaking
#    of Ts) and depressions which causes a double counting
#    of the biphasic episode as two separate episodes.
#    This occurs at: 6:41:32, 16:48:58, 18:33:00,
#    21:21:48, 21:36:10 and 23:36:22.
#    Physiologically each of these represents a single
#    episode of ischemia. At 15:18:52, there is a short
#    axis shift which interrupts the terminal portion of
#    an ischemic episode, resulting in artifactual early
#    termination of the ischemic episode, and the definition
#    of a second episode.
#  Lead 1:
#    At approximately 6:41:36 the terminal portion of the
#    ischemic episode is split into additional episodes -
#    but all represent the resolution phase of the ischemic
#    episode. T wave peaks, T-wave peaking decreases, and
#    finally ST depression resolve.
#    At 7:21:20, double positive peak in ST trend at beginning
#    of this episode is created by the superposition of
#    rate-related ST-depression. At 15:18:52, see note above
#    for lead 0. At the end of this record the data has a
#    number of episodes labeled as "rate-related".
#    At 16:52:48, axis shift annotation set between the end
#    of ischemic episode and local reference.
#  Electrode locations were not recorded.
