I am working on ECG, I designed some circuits and finally I could receive clear ECG signals, but I have an unknown problem, when I finished my tests on my self every thing was ok, but when I tried to get signal from female output signal was extremely low!! In cases that chest lead quality is not good it doesn’t have any problem on men, even in worth case it just could be a bit noisy, but women does not have any signal output. So I think the reason is skin impedance so is it true? How I can solve it that it work for women as good as men.
Any help would be greatly appreciated,
All the best,
