A smartwatch can now measure heart rate variability, blood oxygen, sleep architecture, and the subtle tremor that precedes a seizure. It can notice atrial fibrillation before its wearer feels anything. It can, in principle, save a life.
It can also generate four thousand data points a day that no clinician has time to read. The result is a new kind of inequality: patients who arrive at appointments with more information than their doctors can process, and doctors who are paid to spend twelve minutes with them.
The interpretation gap
The bottleneck is not sensing. It is sense-making. A handful of health systems are experimenting with triage models that read wearable data and surface only the anomalies that matter. Early results suggest the approach catches more real problems and produces fewer false alarms than raw dashboards.
A number is not a diagnosis. It is a question with a timestamp.
The deeper question is who owns the interpretation. If the answer is a platform, then the platform becomes the first clinician most people ever see. That may be fine. It should not be accidental.
