Also, I go for a second cardio version next week. They say I am always in AFib. Then they will discuss an ablation and they did bring that up before but again, not my first choice without more information. Now I wonder why they rushed to do the pacemaker and now I still have AFib. My symptoms have not changed except for the gastric issues. I have had the palpitations, etc. all my life and in my childhood. The fatigue is what sent me to the cardiologist in the first place. But maybe the fatigue was due to something else, as after chemo and radiation, a lot changed. Maybe it was my liver complaining but no real obvious issues in bloodwork. That is why I am being cautious, because I do not like going under anesthesia or being in the hospital for anything. I always seem to "lose a part" in those places. Don't have any left to lose that I don't need.

The pacemaker must have been to regulate the speed of your left ventricle. Many people have what is called 'rapid ventricular response', meaning that the left ventricle wants to keep up with the signal making the left atrium beat chaotically. This is dangerous because it's a tachyarrhythmia (abnormally fast, any HR upwards of 100 BPM). So, as you have found, and as hopefully someone should have made clear to you before the pacemaker, a pacemaker doesn't preclude AF. It might help calm the heart enough with a regulated HR that it makes AF happen less often....which is good. But a pacemaker only regulates the ventricles, not the atrium, and that is why people with a pacemaker can still have AF. They just no longer have RVR, the rapid ventricular rate that becomes more and more dangerous as the hours pile up.
