Apple is rarely ever the absolute first. Usually similar things have existed for a while and apple comes in and makes them much better and more accessible.
Sure, maybe apple is first this time but I have a hard time believing Apple is at the cutting edge of new medical technology.
I believe (could be wrong), that Apple was the first to have a mass-market wearable with a ECG feature. So you don’t even have do look that far to find a refutation.
I don’t know about how innovative these rumored sensors may to comparatively, though.
