#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.
