Answer:

I am not sure of your heart rhythm during the events you describe. If you have electrocardiographic record of such an event, it would be easier to analyse and propose an explanation.

This is very unusual. May relate to vagal tone.

Answer:

I am not aware of any response to weight loss per se. However, it may be possible to restore and maintain sinus rhythm with electrical or chemical cardioversion backed up by anti-arrhythmic therapy. Although there is no evidence to support the role of weight loss, it may help. I am not aware that weight loss achieved by surgery, gastric balloons or anorectic medication would be beneficial and any such therapy has its own adverse effects and complications which would have to weighed against the anticipated benefit.

Answer:

Since you are asymptomatic, I would not advise you to pursue catheter ablation in order to maintain sinus rhythm. Depending on your job and your heart function, you may be able continue working without serious impairment of quality of life.

Answer:

Atrial flutter and intermittent atrial fibrillation frequently co-exist. Alternatively, atrial fibrillation may develop after ablation of typical atrial flutter. Depending upon the frequency of episodes, it may be necessary to take anti-arrhythmic drugs regularly (try a different drug such as Propafenone or Sotalol if regular Flecainide does not work) failing which consider Amiodarone or catheter ablation. Sinus Bradycardia makes it difficult to use anti-arrhythmic drugs in effective doses and can lead to an early recourse to catheter ablation of the atrial fibrillation. Transformation to permanent atrial fibrillation is at present difficult to predict.

Answer:

So-called vagal atrial fibrillation is not a diagnosis precisely because the relationship of activity in the vagus nerve and atrial fibrillation in humans is unknown. There is ongoing research to try and clarify this complex relationship.

Answer:

Atrial fibrillation and atrial flutter may cause or worsen heart failure and be associated with a heart murmur usuallly because heart dilatation can cause a valve to leak. The ablation procedure may have some relationship to the murmur, however, I suggest that you consult a cardiologist and get an echocardiogram to evaluate heart function and establish the cause of the murmur if any.

Answer:

There is some evidence of an association between endurance athletic training for many years and the precocious onset of atrial fibrillation but specific risk factors have not been clarified. I believe that you may consider curtailing your running if an echocardiogram shows signs of dilatation of the left heart chambers, particularly the left atrium although this is unproven.

Answer:

We have published data that indicate that routine prophylactic right sided cavotricuspid isthmus (CTI)ablation is not necessary for patients with AFib. I perform CTI ablation only for patients with documented typical flutter.

Answer:

I do not know the active pharmacologic principal of Rhythmol and Cardizem. Beta blockers are known to impair sexual drive and function.
