Hello Sagan, very interesting share about the mitral valve regurgitation and how it came about. I too have same but its mild to moderate. What a journey! I am looking up the books you recommended too. I do feel that heaviness that comes with being my own advocate and the fact you had to push for the heart monitor made me whince...that is just how it works unfortunately. You are the second person in a week to mention the Pure brand of magnesium. Ordering it today. How do you feel about CoQ10? Any insights? I am tempted to give it a try as I do have issues with supraventricular tachycardia and a small amount of afib still. Thanks for the feedback.
