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).
