Lone atrial fibrillation - questions
by Victric, Jul 21, 2007 12:00AM
Hi,
I'm a fit and healthy 25 year old male, that has recently been diagnosed with paroxysmal atrial fibrillation. The attacks so far have been few, and occur during very heavy exertion and stress. Echo and stress tests have been done, and they are considered normal, according to my doctor. Therefore my diagosis is Lone Atrial Fibrillation.
1. Do you know how common attacks of AF is in my age? How often do you doctors see that? As often as heart attacks?!
2. During my attacks (pulse rate 190) the doctors say I have intermittent aberration. Is that a sign that my conduction system is damaged, or could aberration happen in otherwise healty hearts?
3. I have a very slightly enlarged left atrium. Could this be due to intermittent Mitral Valve Prolapse not seen on my echo? Or are MVP always seen on an echo?
4. Could a past subclinical myocarditis have led to my AF? Are there any tests to see if that is the case?
Thank you for your time!

MVP is a clinical diagnosis confirmed by Echo: hence if it was not sen on an echo then you don't have MVP. There are structural abnormalities which can lead to AF, and since you mention aberration I want you to consider one of the variants of WPW ( wolf-Parkinson-White), a syndrome associated with Afib which is liked to very fast rates of atrial fibrillation passed onto the ventricles. An EP study is generally necessary to document the rarer forms of this disorder, and this is curable with catheter ablation.
Atrial fibrillation is very seldomly seen in young patients with normal hearts: when it is it is usualy associated with thyroid, pulmonary or other endocrine dysfunction. Howver this is by far the most common arrhythmia seen in the elderly.
