Mate. I don’t have to think about it. I know what an ECG is (the clue is in the avatar) And this is a HRM at best. Anyway. Value is an objective thing. And if you think you’re getting good value with this (cough) ‘ECG Machine’ then, that’s the main thing isn’t it?. Cheers!
I suppose we'll just have to disagree. I've built primitive versions of this tech myself (anyone with basic electronic skills can, really) and its good enough to show unusual QT intervals and PVCs. I wouldn't use it for diagnostics, but it's certainly more than a heart rate monitor.
