EPISODE 1. The first episode, in Portland, Oregon occurred around twenty years ago, after Christmas day, about thirty minutes after an extraordinarily large evening meal. I was out walking and bent over to retie my shoe laces. Emergency medical people said my rate was about 175 beats per minute (bpm). In an emergency room of a hospital, a doctor injected a substance (unknown to me now) that stopped the racing and restored my normal rate of about 65 bpm.
EPISODE 5. My fifth episode began on April 29, 2014, after about four months of no tachycardia or irregularity (December 2013 to April 2014). The event started in the evening. The immediate trigger was eating a meal too quickly. I bloated. Then after dinner I bent over to untie my shoe laces. My heart began racing. I could not stop it with deep breathing and back bends. Compression of the heart seems to have been the cause. I began taking 50 mg Metoprolol and 0.25 mg Digoxin. In the following two weeks I went through the familiar stages: (1) At first the medications seem to have little effect; (2) after a few days the heart rate dropped into the 80s; (3) on May 11 (much sooner than in earlier episodes), my heart rate dropped into the 40s-50s. I needed to cut back my walking and walk more slowly too. I reduced my digoxin to 0.125 mg, and then after a few days, deleted it as my heart rate continued to be in the 40s. This episode has shown faster recovery than ever before.
(2) A cumulating effect of the medications. Does the Metoprolol "train" the nerve to fire at a slower rate? I do not know.
(8) Being objective, by which I mean focusing on objects directly in front of and not worrying about real or imaginary events occurring outside of my life. This focusing includes engaging in one task at a time and not multitasking. Often slower is faster.
(9) Chewing my food thoroughly and eating slowly, without stress.
