Prizma Medical Smartphone Case Available Now, page-10

I have had some experience with heart monitoring because of aortic fibrillation and aortic valve replacement. When my heart is monitored there are at least four to six wires connected to my chest. This product Prizma measures via your finger/thumb on the cover as I recall, way less than clinical grade heart monitors.
I’m just confused that the Prizma claims clinical monitoring. Are there any specialists out there that can shed light on one point accuracy?

I’m not attempting a down ramp, I have a ton of shares. I just need to know the potential of this claim.
