Atrial Fibrillation (AFib) Support Group
Atrial fibrillation (AF or afib) is an abnormal heart rhythm (cardiac arrhythmia) which involves the two small, upper heart chambers (the atria). Heart beats in a normal heart begin after electricity generated in the atria by the sinoatrial node spread through the heart and cause contraction of the heart muscle and pumping of blood.
Think about it. What are they going to do? You all know.
"triggered by exercise, stress, stimulants, exertion, etc., then you may have "Adrenergically-Mediated" A-Fib. People with structural heart disease seem more prone to Adrenergic A-Fib. But if your A-Fib occurs at night, after a meal, when resting after exercising, or when you have digestive problems, then you may have "Vagally-Mediated" A-Fib. People with Lone A-Fib seem more prone to Vagal A-Fib. (Many people have a mix of both Adrenergic and Vagal A-Fib.) (Perhaps A-Fib begins as a nervous system problem, then becomes a heart problem after the arrhythmia is established.)
It's important to determine if you have one or the other so that you can better identify what triggers your A-Fib, and because the treatments are often different for each. For example, beta-blockers usually don't work well with Vagal A-Fib. (Though it's difficult to generalize about A-Fib treatments, because each person reacts so individually.) Current research hasn't indicated yet whether Pulmonary Vein Ablation is more or less effective or appropriate for Adrenergic than for Vagal A-Fib. However, it seems that both Adrenergic and Vagal A-Fib are focal in origin (come from specific points or spots in the heart), and can presumably be cured by current Pulmonary Vein Ablation (Isolation) procedures."

My G.P. wants to put me full time on Atenolol. I emailed him back and said that I wanted to see a cardiologist, and he obliged.
I've read in a number or reputable places that Atenolol can actually turn infrequent afib of the Vagal type into permanent afib, so I'm really concerned about this. At the same time, I don't want to be one of these guys who thinks they know better than a Dr. because they've read something on the internet.
I'm going to take it slow and walk through this one step at a time.
But it looks like there may not be clear cut answers for each individual, perhaps especially early on.
Thanks everyone for this forum and your information.
