+\fB\s12TABLES OF BEATS AND RHYTHMS\s10\fP
+
+
+.PP
+The following pages contain tables that summarize the contents of the
+database.
+These tables duplicate some of the contents of the previous
+section (Notes), to which reference should be made for more details.
+The first two tables list the beat types and rhythms for
+each half-hour record in its entirety.  The last two tables show the
+same information, but for the AAMI-defined ``test periods'' only
+(i.e., excluding the first five minutes of each record).
+.PP
+The column headings for the beat tables show the AHA annotation codes
+(N, V, F, E, P, Q, and O) above the symbols used for the database annotations
+elsewhere in this book.
+A complete list of these symbols, as well as the abbreviations used as
+the column headings for the rhythm tables, may be found on page viii.
+.PP
+The beat tables show the number of beats of each type in each record.
+The rhythm tables show the total duration of each rhythm observed in each
+record in minutes and seconds (rounded to the nearest second).
