Taking the P wave



detail of one of the samples bearing the satin ECG

Okay now I don't want to get too technical on this but you might remember the post about the ECG data http://www.karinathompsontextiles.blogspot.co.uk/2013_01_01_archive.html
The ECG had 3 lines of data.  My technical adviser (Nicky) suggested that if I was to use a single line that it should be the bottom line as that was coherent throughout the run.  It clearly shows what my heart was doing from rest to peak to post-run.
I started cleaning up the data and programming part of it into a lovely 4mm wide satin embroidery.  After a couple of technical problems I finally could stitch it out in a way that I was happy.  I could repeat it and build it into lengths in a way that I will do on the final piece.  I was really happy with the results.

I could stitch the wave form out over the reprogrammed footprints and over densely stitched echocardiogrammes.  It felt like the piece was finally taking shape; it was looking really lovely

However working on the other 2 wave forms I suddenly realised that I had actually left out part of a heart beat and that every other beat had no P-wave.  That would be pretty serious if my heart was really doing that!  No points for attention to detail.......
