I find it interesting that all the comments here talk about Afib sessions that do not result in going to the hospital. I have been told that I should call 911 if I have an attack. The challenge is that as soon as I think I should call 911 it quits! I have a pacemaker because my heart rate dropped below 55 and I was blacking out. My heart rate at age 16 was 72! At my last check-up of my pacemaker the technician raised the heart beat to 81. After a few weeks, I asked for it to be reduced and he refused. A few weeks ago, I had a phone call session with my cardiologist and he told me that my heartbeat wasn't 81! Fortunately, I have kept copies of my heartbeat sessions and it clearly shows that before the change it was lower and the pacemaker is set at 81 beats a minute. I am concerned that this higher rate may have a negative impact on my heart. I would like to know more about the positive and negative benefits of raising the heartbeat beyond what was my normal since my teenage years. Any information would be helpful. I am concerned that I suffering from "senior dismissal" or what you want to call it, when you are a senior and your concerns are dismissed. BTW I didn't have any blackouts until I was 80. Now I am 84! I hate mentioning my age. I used to be proud of it. Now it seems to bring negative reactions. I took a cognitive test a few years ago and I aced it. 30/30! My doctor wasn't sure he could do as well.
