The focus is usually right at the junction of the vein and heart tissue. Glad to be of help.
Thank you for that piece of information. How does tissue in the pulmonary vien initiate afib? Perhaps that is a difficult question to answer. I would have thought the stimulus would be confined within the heart tissue itself.
One other observation I have noticed and would appreciate your thoughts on - as I said earlier I recently suffered a decent cold where my resting heart rate elevated significantly. This is still the case although I am getting over it now. The swallow trigger has shut off completely since this cold came on. Now that I am getting better I am starting to experience muscle twitches especially concentrated in the left Pectoral region. I sometimes wonder if they are cardiac twitches or skeletal. I suspect skeletal in that they seem very surficial and the beat of the heart does not react to them. Is there some connection that could account for this? I sometimes wonder if some neuromuscular disorder could in fact be at work here.
Thanks Again

You are correct that afib ablation is not an easy thing and is still in its early stages. However, in some individuals the afib starts from a single focus, usually in the pulmonary veins, that can be ablated using special techniques. A large academic center near you should be doing it and if not we are doing it here and you can make an appointment in the electrophysiology clinic for evaluation.
When you say afib ablation exactly how would that be done? I understand the ablation idea after having gone through an EP study with no ablation. I understand that afib is a tough thing to attack throught this procedure. Usually procedures such as Maze etc are considered. I suppose it may be due to the presence of a single foci which is targeted for ablation.

You are asking a very good question and one that there is not well researched answers. It is true that people with higher vagal tones and lower heart rates are predisposed to afib. Possibly this is because the foci where the afib starts does not have time to discharge at a higher heart rate. There are no trials of scopolamine for this and I would be rather leary of taking it on a regular basis. A pacemaker set to a higher rate would be one option I suppose but your best option is to have an afib ablation. Yours would probably be amenable to this procedure. We are doing afib ablations here and if you would like to be considered for this procedure please make an appointment with Dr. Andre Natalie by calling the number below.
