hi to all, if any body could help me out in conversion of ECG signal to heart rate , to send it as a message to any mobile for medical usage , i am using gsm modem for transmissiom. also please suggest any good gsm modem available in india and should be cheap for laboratory purpouse. which microcontroller could be easily interfaced for ecg applications in 8051 microcontrollers series. thanks for helping bye take care

A good source of info: http://en.wikipedia.org/wiki/Electrocardiogram Suggestion of good GSM modules (modem) that is available in india: (They've got different models, used them once, never had any hassles) http://www.wavecom.com/modules/movie/scenes/locator/?fuseAction=distributors&country=97 As far as a microcontroller is concerned, (If I am forced to use a 8051), my choice for this application would be the following: http://focus.ti.com/docs/prod/folders/print/msc1202y2.html Cheers

There are other remote ecg monitoring products in other filings to inspect as well. BTW: does anyone have any info on an old Prospirit HRM similar to the Timex cited above? I thought that I had archived documentation on it years ago but I can no longer locate it; the units would be a good basis for a project I am contemplating. I still haven't found the FCC filing for this one; perhaps it will turn up under some other product description. Regards, Michael

Basic documentation is available from the Taiwanese Mfg.'s site. The device does not have an FCC OET record nor does the manufacturer have _any_ FCC records, however the device radiates at 130kHz and has a 'CE number' sticker affixed to it. Please see my post inquiring about availability of CE certification data. Regards, Michael
