+The following pages contain notes and statistics that describe the contents of
+each record.
+The leads used for the upper and lower signals are given for each record
+immediately following the record number.
+Beat counts are given for the first five minutes of each record and
+the remainder of the record (the AAMI-defined ``learning'' and ``test''
+periods, respectively).
+Note that the totals include two types of non-beats (blocked APCs and
+ventricular flutter waves) for those few records in which they occur.
+The total duration of each record is 30 minutes and 5.556 seconds;  durations
+noted below are rounded to the nearest second, and may not sum to exactly
+30:06 because of accumulated rounding error.
+Heart rates are given in beats per minute measured over 3 R-R intervals.
