Tables of beats and rhythms

These tables summarize the contents of the database. These tables duplicate some of the contents of the previous section, 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 EC38-defined ``test periods'' only (i.e., excluding the first five minutes of each record).

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 directory. For a complete list of these symbols, as well as the abbreviations used as the column headings for the rhythm tables, see Symbols.

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).
