If you have been following my blog for a while, some time ago I was having issues with my heart rate skyrocketing above 200. I even had to have a Holter monitor put on for 48-hours. They had detected that my heart rate dropped to 35 during strenuous physical activity, and then it had gone up to 189 or so during rest. This is normal. My cardiologist, at the time, said that it was a fluke and that it would never happen again. He was wrong. It has happened three times since, and two of those times happen within this past week.
