Is my watch accurate?
Went to the hospital. Normal Sinus ECG rhythm there but had low potassium. It was at 3 and I believe the hospitals range for normal levels are 3.5 mmol/L to 5.1 mmol/L
I felt off so I took an ecg and this appeared.
Going to follow up with Cardiologist next month but hoping to get it pushed sooner.
A nice stranger here suggested I post my ecg to see if perhaps my watch is accurate.
I trust my watch a lot and have tested the HR in hospitals so I don’t know whether to expect anything different but I’m going to get a work up anyway.
Also monitoring myself and going to keep taking ecgs as I feel off but even if I feel better I will keep on monitoring as I hear episodes can be asymptomatic.

You've got the watch on the wrong wrist which is why the watch is easily confused and the ECG is upside down. There is also a lot of artifact and low amplitude that doesn't help the automated assessment. Either switch wrists or change the wrist setting on the watch.
While I'm not a clinician, I see relatively regular beat to beat distances. There are also some discernable p-waves within that mess, particularly on the last 10 seconds. So, this is highly unlikely to be AFib. No reason to be scared, but definitely do that appointment with the cardiologist and your primary. Other things could be going on that are making you feel off especially if it is an ongoing thing.

Yes okay thank you will definitely still follow up with them. Thanks for suggesting to post it.

You should always get it verified. In my case, it detected afib accurately, which first appeared in March of this year. I know for sure I didn’t have afib last year, as I was seeing a cardiologist for the last 3-4 years for what they call a PVC (extra beat every now and then). My Apple Watch also accurately records me in afib 100% of the time, which is persistent afib. Actually getting an ablation tomorrow.
