The Smart Watch Diagnosed My Heart. My Doctor Agreed. I Felt Nothing

The watch flagged an irregular rhythm on a Tuesday. The cardiologist confirmed it on Thursday. The machine was right, and the machine was the one who told me, and I have not felt the same about my own body since.

The alert came at 4:17 in the afternoon. The watch vibrated, and the screen said irregular rhythm detected, and it offered to share the data with my doctor. It did not ask if I was okay. It did not ask if I was scared. It asked if it could share the data, which is the only question a machine knows how to ask.

I felt fine. That is the strange part. I had felt fine for weeks. The watch had been collecting data I could not feel, analyzing a rhythm I could not hear, and it had found something my body had not thought to mention. I went to the doctor, mostly to prove the watch wrong. The doctor ran the tests. The doctor looked at the printout. The doctor said the watch was right.

The diagnosis was manageable. Medication, monitoring, a few small changes. My doctor was excellent and kind. But I have not been able to shake the feeling that my body reported to the machine before it reported to me, that there is now a version of my health that exists in a data center, more current than the version I live in.

Everyone says the technology saved me. It did, probably. It caught something my doctor would have caught later, and later can be too late. I am grateful. I am also hollow. I have started checking the watch the way you check a weather app, and I have started to believe the watch over my own body, because the watch is never wrong, and my body has lied to me before.

Here is the sentence I keep turning over: I used to know my body by living in it. Now I know it by reading its reports. The cardiologist says I am fine, with monitoring. The watch says I am fine, with data. I am fine, and the fine-ness belongs to someone else now, and I am wearing the someone else on my wrist, and I have started to think that the heart the machine watches is not the heart I was born with, but a smaller, more legible one, that beats for the dashboard.
