\fB\s+2FULL\-DISCLOSURE ECG PLOTS\s-2\fR


.PP
This section contains annotated ``full-disclosure'' ECG plots for the
entire database.  Each record is presented on two facing pages.  Each
page contains fifteen one-minute segments.  Each segment contains a pair
of ECG traces with annotation labels placed between them.  Each label is
placed so that the fiducial mark for the annotation corresponds to the
left edge of the label.  The meanings of the various labels are given
in the table on page viii.

The scale is 2.5 mm/sec and 1 mm/mV (i.e., one-tenth the standard scale
for ECG chart recordings).  To improve the legibility of these plots, the
ECG signals were digitally low-pass filtered with a nine-point moving average
filter before plotting them;  for this reason, high-frequency noise appears
smaller in amplitude in these plots than in the unfiltered high-resolution
strips which begin on page 98.
.PP
At the top and bottom of
each page is a time scale with one-second intervals marked;  five-second
intervals are designated with large ticks on these scales.  To the left
and right of each segment are the times of the beginning and end
of the segment (in minutes and seconds from
the beginning of the record).  The last segment for each record begins at
29 minutes, and ends at 30 minutes and 5.556 seconds (the end of the record).
