Tom Bridge, on Cannonball:

This afternoon, I was helping a client move offices, mostly just deconstructing a simple network rack and moving access points into new space. I was doing some physical work, but nothing anyone would mistake for exercise. But, then I felt it. My heart was pounding. I got dizzy. Tunnel vision. I had to sit down.

I took my heart rate on the watch and it was over 200. I spent five years as a competitive swimmer, and to my knowledge I never got above 195. Even riding up Box Hill on Zwift didn’t get me over 170 this winter. 200 is scary territory. I remembered the ECG functionality, and googled how it worked. I took a reading.

I didn’t know how to read it, and I knew I was in a bit of trouble, so I had a coworker take me up to MedStar Washington Hospital Center, a mile or two away. Triage saw me rapidly, and I unlocked my phone to show the nurse. She was setting up a more complicated EKG, but because my heart rate had dropped back toward normal, it might not have any clear result they could read beyond just normal operation.

As soon as the tele-doc came on screen, the nurse rotated my phone and put it up to the camera to show the doctor the rapid rhythm from half an hour earlier.

“Oh, that’s an SVT,” he said immediately.

I didn’t see what it had to do with Ford’s Special Vehicle Team, but he clarified that he meant Supraventricular Tachycardia. They wanted to make sure labs were taken, and that nothing abnormal in my blood work showed a more troubling cause. But the diagnosis was there in an instant, thanks to my wrist watch.

At the intersection of technology, liberal arts, and saving lives.
