I agree that it would be cool to see. Maybe some kind of marker or so on the HR graph in SA. But I personally tend to wear my watch loose when not working out and considering weight of the unit and not the most reliable valencell sensor and no continuous measurement (only each 12min or so), it’s probably more likely that each deviation in HR graph is an error that an indication of heart problem. And during activity it’s probably even more so the case, since active arm movement tends to make my graph pretty noisy, for HR strap also. I thought apple had specific technology to provide this feature and for a “heart scan” you should stay still and they say themselves that one shouldn’t rely on this measurement and visit a doctor.
