So far my hurdles have been unanticipated. Friday morning I had a bout with atrial fibrillation, my heart rate was racing and my blood pressure was dropping. Needless to say I drew the undivided attention of the nurses and doctors. 24 hours later after being stabbed, punctured and pumped full of drugs and fluid my heart is finally back into normal rhythm. Yesterday would have been a much nicer day without this complication. I have had atrial fibrillation for several years. It only shows up every year or so and usually goes back into normal rhythm without help or coercion.
