Our expert says:
I have a feeling that measurement is an error. I say this because I have seen the exact number myself, and I think it might be, for whatever reason (maybe an engineer can explain it), the number that you get with interference from electrical sources. If it was a tachycardia or some physiological value, then it wouldn't stick at 219, it would be say 220, or 215, then drop off and return to normal. It sounds like it goes to that number and then returns, and that is not typical, and I think not physiological.
So I have a feeling it's technology and not physiology. That said, it's never a bad idea to be safe rather than sorry, so you could consider doing a stress ECG to see whether there is some fibrillation or underlying conditions.
