This will work short-term sure, but after about lets say, 3 years of no adverse findings, the average person will not take it seriously anymore.

Huh? I get a blood panel every year and 90% of the things it looks for are normal year after year. But there is always 1 or 2 things flagged that I need to pay attention to.

An ECG if it was just part of the normal yearly panel of things that get looked at I don't think ppl will stop doing it just because it doesn't find something right away
