To run the program (it is a Perl script), libRASCH version 0.8.0pre2 or greater and the Perl API bindings have to be installed (see the INSTALL file coming with the distribution. You will get libRASCH from http://www.librasch.org/librasch/download_lib.html using the latest pre-realease version. If you want to use the Windows binary distribution, ActiveState Perl 5.8 is supported with a pre-compiled binary Perl module (which will be installed when installing libRASCH). Usage of the program: ============== perl get_qt_cinc_2006.pl --template=templ-file --file=out-file [--detect] [--ch=X] [--check-morphology] [--skip-powerline] with --template=templ-file selecting the template of the entry-form --file=out-file selecting the name of the final entry-form --detect if given, a beat detection is performed, if not, the beat information (position and annotation) which is available is used --ch=X do the QT measurement using channel 'X' (channel-numbers start with 0 -> lead I is 0, lead II is 1, ...) --check-morphology if given, the morphologies of the QRS complexes and T-waves are forced to be the same for all beats (e.g. when the Q-wave on some beats is too small to be detected but seen on the majority of the beats, the threshold used to detect Q-waves is reduced so if small Q-waves will be detected) --skip-powerline if given, the powerline-noise filter is NOT applied to the raw ecg data the directory(s) with the ECGs to process Example ===== perl get_qt_cinc_2006.pl --detect --ch=1 --template=template_div3.txt --file=results_div3.txt ./patient* Do the QT measurements on the ECGs found in the directories 'patient*', using the file 'template_div3.txt' as entry-form template and write the final entry-fom to the file 'results_div3.txt'. The QT measurement is performed on channel 1 which is lead II.
