I got one for free for a demo and while it was interesting, I can't think of a good use case. A single lead ECG is not useful for much more than heart rate, and there are already many interesting ways to get that ( light sensor on phone ) that i dont know if it has much more utility from extra hardware. Perhaps if you have lqts, it can flag it but otherwise very very few usecases.
