oseawrapper
Wrapper application to parse a input data file through the Open Source ECG Analyzer by E. P. Limited.

Compilation
No known exotic dependencies. Type make and you should be done.
Working on Red Hat Enterprise Linux Workstation release 6.5 (Santiago).
Usage
./oseawrapper [input datafile] (output datafile)
Input datafile
A file containing a single ECG integer sample per line. The data should be formatted to fulfil the following conditions:
- Normalised to 5 mV/LSB (200 A-to-D units per mV)
- 200 Hz sample rate, although this algorithm should work beyond this
Output datafile
Output is sent to a file or to stdout if not specified. Each detected heart beat is reported as a tab-delimited index, delay, beat type and beat match output.
The index is the sample offset when the beat was detected. The next value, delay is the delay in samples for the OSEA algorithm to detect the heart beat, therefore the beat was detected at index - delay samples. The beat type is 1 for a normal R-wave, 5 for a PVC (Premature Ventricular Contraction) and 13 for an unknown beat. The beat match is provided for an unknown debugging purpose.
