Most times my heart stops a beat for a second.
I had a similar experience my FitBit watch recorded as Afib. It came on suddenly without serious symptoms so I waited for it to pass. When it did not I went to my doctor, had an ekg which confirmed Afib. He got me to a cardiologist that afternoon. I had a successful Ablation 6 weeks ago.
Don’t wait.

You should get checked by your doc.
