I should say that the often book focused on heart conditions and arrhythmias other than those of direct, personal interest to me. The segment on atrial flutter was relatively brief but quite informative; the book made almost no mention of heart block.
The Haywire Heart was a useful and informative read. It seemed well researched, rational, and balanced. Its illustrations were also useful. While I might have quibbled a bit with its organization and coverage, I would definitely recommend it for anyone seeking knowledge and perspective on (aerobic) exercise and risks to heart health.
An echocardiogram was advised, which showed severe left atrial dilatation, which I accept is due to damage resulting from excessive training training for marathons (it's well described in the book). So, I was referred to a cardiologist, who noted that I have a resting heart rate of 40 bpm (sinus bradycardia, not heart block), so he advised me to have an artificial pacemaker.
This book was very useful in providing alternative advice. My resting heart occasionally drops to 34 bpm (anything above 30 bpm is acceptable as normal in athletes) with no symptoms and a completely normal unchanged blood pressure.
Most of the book on arrhythmias doesn't appear to apply to me - I'm never aware of my heart beat or have shortness of breath exercising or at other times. And the chapter advising supplements to me just appears to be junk science.
I'm still being investigated. The next step is to have a Holter monitor, which might provide some useful information. Or not.
I think the vasovagal attack was due to jet lag (I'd flown from Munich to Perth 2 days earlier - a 17 hour flight with a 6 hour time zone change, so there was probably some tiredness involved). And the Red Cross had recently changed their procedure for plasma donations, not replacing the 900 ml of plasma donated with a litre of saline till the end, so there was probably some low blood volume involved too.
I don't think I need to worry much. I'm retired from the heavy marathon training, so that's not a problem. I'm currently doing cardio' workouts in a gym, which are comfortable, to maintain fitness.
The book has provided me good reasons for declining a pacemaker.
