I have had atrial fibrillation (AFib) for approximately 40 years (from my mid-20s to mid-60s), but the disease has progressed very slowly. I am still paroxysmal (intermittent) with minimal AFib burden; in fact, I am in sinus rhythm over 99% of the time. My episodes (a handful a year) typically last around half a day, and I've never needed medical intervention to terminate an episode. I've never had an episode lasting over a day. I've never had a stroke, and I have an otherwise normal heart with normal-sized atria. In this book I will explain how I have done it, naturally, without the medical intervention of drugs (except a few, optional ones, primarily during episodes), electroshock, ablation, or surgery. I am not a doctor, but I did graduate from the University of California, Berkeley with a degree in astronomy and physics. I also worked at NASA's Jet Propulsion Lab (JPL) in the space program.
