Information on the vagus nerve has been discussed often on this website and many websites offer information. I recently read this one drsircus.com/medicine/funct... and thought others could be interested. I suspect our heart issues may be influenced by other organs in ways doctors do not fully understand; and correcting these issues, might be more effective than attempting to fix the heart with medication or ablations. By trying various treatments available with the Scenar device that I purchased, I have noticed that I can positively influence the heart. One treatment on the stomach; that I tried, to my surprise immediately stopped an AF episode. Coincidence, or something more, I will learn should I be able to do it again. I have not had AF since to verify this. I have been doing the stomach treatment daily so maybe this is why AF has not reoccurred. One can always hope.
