If its just once , may be got to do with bad grip on the wrist. But if it is continuous readings for a few minutes, you should get it checked. 48 hr is fine at rest, 174 is not.
You can also do an ECG at home and get it reviewed from an app called QALY. That is also pretty accurate and i use it periodically to track ecgs.
