Thanks @exboater I agree that triggers do exist for the majority of afib sufferers, particular those for whom there are no underlying structural causes such as rheumatic heart disease and multiple valve surgeries or even heart attacks etc. It is however very likely that afib comes and goes for some of us regardless of what we do or not do. I happen to be in this category ;-( One learns a lot when dealing with it for over 20 years....
Glad to hear you have no issues with your pacemaker and that it is helping to keep you in sinus. It is still option #5 for me, thank goodness.
