I spent a little more time testing my electrocardiogram system last night. This time I tested it at home with the National Instruments USB acquisition. I tried to get a baseline ECG and then collected data while playing Tekken 5 Dark Resurrection. The signals looked terrible compared to what I saw in the lab with the oscilloscope, however, a heart rate could be seen. I will spend some time in the coming weeks making my portable system work as well as the lab setup. A schematic will be available once I get some of the noise issues taken care of. The PDF below is a side by side plot comparing ten seconds of baseline to ten seconds of Tekken play with an average 60BPM in the former and 80BPM in the latter. The two text files are the data for both sets. They are ASCII files with two columns. The left column is a millisecond time stamp and the right column is a recorded voltage.
