I've spent the last few days reading through past posts on the vagal issue in AF, and researching online. But I can't seem to get a clear, simple concept of how exactly, the vagus nerve contributes to starting and stopping AF!
I understand the basic 'vagus nerve slows the heart rate' concept. Also, that a 'high' vagal tone is thought to be a good thing, as it improves the function of many body systems.
However, there are posts and online articles that promote both vagal calming AND increased toning. This is my first area of confusion, which then leads to more befuddling when I read about AF being triggered by either a slowed heart rate (well-toned vagus nerve), or by ectopics and tachycardia (low vagal tone).
So I am reaching out to any lovely people out there, who have managed to attain a coherent understanding of these processes! Thank you in advance :o)
