Name

sumstats - derive aggregate statistics from bxb, rxr, etc., line-format output

Synopsis

sumstats file

Description

This program derives the aggregate statistics described in sections 3.5.2 and 3.5.3 of the American National Standard, Testing and reporting performance results of cardiac rhythm and ST segment measurement algorithms (ANSI/AAMI EC57:1998, based on the earlier AAMI ECAR:1987), and in sections 4.2.14.4.1 and 4.2.14.4.2 of the American National Standard, Ambulatory electrocardiographs (ANSI/AAMI EC38:1998).

To use this program, first generate a line-format report file using the -l or -L options of bxb(1) , epicmp(1) , mxm(1) , or rxr(1) . This file must include column headings so that sumstats can recognize the file type. Output is written to the standard output; it includes a copy of the input file, with aggregate statistics appended at the end.
