It wasn't until I got my pacemaker that I was diagnosed with Afib. I am apparently one of the lucky 30% who get it after getting a pacemaker. At my follow-up appointment they told me I also had flutter. I was having troublesome symptoms such as feeling my heart racing and just being constantly aware of the heartbeats. I had an ablation about a week ago and those symptoms went away, but I am still fatigued. My smart watch has detected some Afib, but I am not sure how reliable that is. Looking forward to my next appointment to see what the prognosis is.
