The persistent monitoring afforded by devices such as Apple Watch will directly lead to an increase in the detection rate of any condition that they are capable of detecting. These new detections will be conditions that had been previously undetected. Whether you class these as false positives (because the existing test suite doesn't detect them) or false negatives (because the existing test suite should have detected them) is perhaps a matter for debate. The practical outcome is more people living healthier lives because their persistent malaise has finally been identified. At first I was wondering how scheduling someone for a long-term ECG would cause damage, then I remembered that this feature will only become available in the USA soon. Given that the USA is a country where unexpected health care can destroy a person's life through either bankruptcy or the curse of being a woman/person of colour, yes I agree that detecting a previously undetectable condition could cause damage.
