i a trying to make wireless ecg.can u pls suggest me where can i get its circuit diagram?
Do you really think that "wireless ecg" is an adequate specification to be able to identify a single circuit diagram?!
With no context, it's not even certain what "ECG" might stand for - presumably you don't mean this ECG: http://www.ecg.ecn.cz do you?
And in what way do you want this device to be "wireless"?
etc, etc, etc...
