.TH SUMSTATS 1 "22 November 2002" "WFDB 10.3.0" "WFDB Applications Guide" .SH NAME sumstats \- derive aggregate statistics from bxb, rxr, etc., line-format output .SH SYNOPSIS \fBsumstats\fR \fIfile\fR .SH DESCRIPTION .PP This program derives the aggregate statistics described in sections 3.5.2 and 3.5.3 of the American National Standard, \fITesting and reporting performance results of cardiac rhythm and ST segment measurement algorithms\fR (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, \fIAmbulatory electrocardiographs\fR (ANSI/AAMI EC38:1998). .PP To use this program, first generate a line-format report \fIfile\fR using the \fB-l\fR or \fB-L\fR options of \fBbxb\fR(1), \fBepicmp\fR(1), \fBmxm\fR(1), or \fBrxr\fR(1). This file must include column headings so that \fBsumstats\fR 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. .SH SEE ALSO \fBbxb\fR(1), \fBecgeval\fR(1), \fBepicmp\fR(1), \fBmxm\fR(1), \fBplotstm\fR(1), \fBrxr\fR(1) .HP \fIEvaluating ECG Analyzers\fR (in the \fIWFDB Applications Guide\fR) .HP \fIAmerican National Standard ANSI/AAMI EC38:1998, Ambulatory Electrocardiographs\fR .HP \fITesting and Reporting Performance Results of Cardiac Rhythm and ST Segment Measurement Algorithms\fR (publication AAMI EC57:1998) .PP The last two publications are available from AAMI, 1110 N Glebe Road, Suite 220, Arlington, VA 22201 USA (http://www.aami.org/). .SH AUTHOR George B.
