I was looking into the hardware requirements of an ECG recorder. I found this article with code in C.

Would a Propeller significantly simplify the DSP. Given a front end in-accordance with the safety regs, How much strip chart time could we log on our bigger SD cards?

    I believe that will depend entirely on the format of the data you want to log. FSRW 2.6 can save at a consistent throughput of about 1 megabyte per second, which may be a bit overkill for your app (unless you save 16-bit values at a sample rate of 500ksps? [8^). A 2GB card, storing 1000 16-bit samples per second lets you record about 12.4 days worth of data.
